88 Foxbody 5.0 Driveshaft Issue! Need Help

[James Hood]

I have 88 Ford Foxbody 5.0 many upgrades to motor . Anyway T5 tranny went out . Decided to go with a Tremec an have it converted from a 5spd to a 6spd manual. Sent it to the shop . They tell me they are having drive shaft custom made .

Drive shaft comes in an it’s the same length as the original. So they send it back because it need to be cut shorter. So they send it back with the measurements that the drive shaft needs to be to fit . An it come back an it still don’t fit because someone didn’t know how to use a measuring tape . So now I’m waiting on a lift to open up so they can re measure a send it back out . Keep in mind this has been over 4 month period . An I have already paid a total of 6400 dollars . Can anyone tell me what’s the correct driveshaft length that will work for the set up I’ve just explained .
Thanks for your Help

Welcome to !

I won't lie, it sounds like the guy working on the car isn't too experienced with modifications like this. It's not hard, and the driveshaft shop should have given him directions since different shops ask for measurements from different locations. Or, worse comes to worse, they use the original driveshaft and figure out how much shorter it would need to be.

Unfortunately I don't have a specific answer to your question. Maybe someone else does? I moved your thread to the Fox Tech section so more eyes could see it. Hopefully someone will be along shortly who can help more than I....

LMR sells T-56 conversion shafts. These are an off-the-shelf item. No need to measure now unless there is something custom or unique about your setup. You'll need to select the right one for your trans application. $500 and a week for shipping and you can wrap this up.

Shove the yolk all the way u in the transmission. Measure from the centerline of where the u-joint would be on the yolk to the flat flange on the rear end if it’s an 8.8. Do this at ride height. This is the measurement you provide to the driveshaft builder and they will subtract about 3/4”.

And like Mustang5L5 pointed out why do this if you can just buy one. Shop should pay for it.
