Aftermarket seat help

Anyone using either Jegs GS-1 or Summits G1159 seats in either a '69 or '70 fastback? I have also been looking at the TMI sport seat upholstery for the '69/70 Mach I seats. I'm most concerned with both the seat bottom height and the seat back height. Right now my stock seat sits higher in my '70 than my friends stock seat sits in his '69.:shrug: My legs hit the bottom of my steering wheel and I don't want the seat backs to look too tall. I know that some people have cut down or removed the seat platform and I may have to do that as well. Any advice/pics would be helpful. Thanks in advance.

someone probably replaced the floors and/or the seat pans in your car at one time and used the coupe seat platforms which are taller than the fastback ones, not very many people know about this so if the seat pans were replaced i'm sure whoever did it had no idea they were different. it's also people that someone on the assembly line screwed up and installed the wrong ones originally or someone did the seat pan mod to your buddies car.


do a search for seat pan mod and you should find a write-up on how to lower the pan and get more leg room too. if you can't find it here it was on Mustangs Plus' website at one time as well and can probably still be found there.

also do a search for Dark Buddha's write-up on his high back seat conversion, he used some fiero (i think) seat side brackets that allow the seat to recline, it's really cool how they did it, add the sport seat conversion to that and you'll have a really nice set of modern/classic seats.

EDIT: note that these were just a trial run at the seats and they never finished them because he had always wanted a set of Fiero seats and found a good deal on some so he went that way instead. i would personally put the seat brackets under the upholstery and i believe that was the plan with his as well. with the sport seat conversion and this reclining mod you could have some super cool seats for your car.
 
Thanks B, I had no idea that they made different seat platform heights. I'll bet you're right that coupe pans were installed.

I'll definitely cut them down when I install new seats, I just have to decide whether to re-upholster my Mach seats w/ the TMI kit or get aftermarket seats.

One one hand, I think the TMI kits are a great improvement if you want to keep the stock look. On the other, I'm not going for a stock look but I don't like the massive seat backs of most racing seats and the Pro-car rally seats look a little retro. Decision, decisions... I'd love to see pics if anybody has upgraded their seats in a '69 or '70.

My other issue with my interior is if I do the seats now I might as well replace the carpeting. And if I do that the headliner needs to be done, and the sail panels, and... Oh, time and money. Just never enough.:rolleyes:
 
if it makes you feel any better i wasn't aware of the different pans until recently either. if you modify the pans you'll probably need to do the carpet then but you can always wait on the headliner on a bit if you want.

i'd seriously consider doing the sport seat conversion and the adjustable/reclining seat mod to the seat if it were me. in fact i did consider it but since i decided to the deluxe seat upholstery which is different from the mach 1 upholstery and they don't make a matching rear set for the mach upholstery for the coupe i decided against it. also, since i decided to sell the car anyway i wanted to do as little modification work as possible so it would appeal to more buyers, oh well, gotta buy a house for the family so it's for a good cause but i just hope it goes to someone who will take care of it.

Yeah, I'm going to have to do the interior in phases do to cost for sure. I was planning on replacing my dash and upgrading the gauge cluster first but I may do the seats first instead. I also have some trim pieces I need to buy and/or refinish on the exterior that need to be done.

I had to do the same thing a while back. I had a fairly rare British sports car that my father had raced and I was planning on restoring but decided to sell it to buy our first house. Although I would love still have the car, the reality is that I would never have had the $$ to properly restore the car back then and it really helped us get into the house and the guy that bought it wound up restoring it and racing it in a vintage racing series which is pretty cool. Even now I don't have the kind of $$ to do all the upgrades to my Stang as quickly as I would like, the car is mostly complete and I love driving it. Thanks for your help and input!!

well reality for me is a bit different since the car is already completely finished, i wouldn't be able to sell it for enough to really help unless it was, not only that it was my first car and i've had it for going on 24 years now, so selling it is going to hurt quite a bit but i do have a 69 cougar project to help ease the pain a little. still, selling the stang is not something i'm really looking forward to, however i am excited about about doing the cougar, especially since i will be able to it exactly the way i wanted to do the stang but didn't because i decided to make it appeal to more people when i sell it. it was about 3/4 done when i decided to sell it so i had to sidestep/backup on some things and completely rethink others when i decided to sell it but because of that i now have a bunch of left over parts that i'll use on the cougar, things like my TCP rack, 68 stang overhead console, intermittent wipers, wheels, tilt column, rear defogger, original C90X aluminum ford muscle parts intake, power trunk release, fox body seats, etc. should be a fun project and i have a parts list of stuff to get for the restomod part of it a mile long but the replacement parts list is tiny since the car is a 75,000 mile original survivor car. it needs paint, weatherstripping, carpet and probably a headliner, otherwise the car is a totally rust free, solid project that doen't even need any real bodywork, it has the usual parking lot dings but that's it.

in case you can't tell i'm really happy to be getting this car, especially for the $1200 price tag of which i've already paid $900 of. once the stang is sold $10k is going to the house and the rest will go to the cougar, that should leave me enough to most if not all of the basic stuff i want to do to it and the rest will come with time and income tax checks. :D
