question about rear ends

[brtnstrns]

i currently have a 200 ci with a 3 spd manual transmission. What i was wondering is if i wanted to swap to a V8 rear end would i also have to switch the driveshaft? Or would a V8 rear end work with the same drive shaft as i have now. I want to get a new rear end so I can have 5 lugs in the back with discs. I already have discs up front and they're capable of being 5 lugs...as long as i put the studs in those holes. Also so when I do a V8 swap in a couple of years i'll alreaedy have the rear end. So will i have to switch anything else besides the rear end if i wanted a v8 rear end?

As for the driveshaft, maybe. I'd wait and see after installing the rearend.

you would need new front spindles to upgrade the front to 5 lug also.

sounds to me like he might have 5 lug front spindles???

maybe not, he said the rotors could be 4 or 5 lug.

the rotors have holes for both 4 lug and 5 lug. It just depends on where you put the studs

you wouldnt need to switch your driveshaft if you changed to a V8 rearend. The only difference in the rearends, to my knowledge, is the axles and the lugs on the end of them.

 

[DukeGnarley]

you do need to make sure you have the V-8 spindles though, there is a diffrence between the V-8 spindles and the I-6 ones.

I am going to see...

I have a 67 pony that was a I6 that was partly converted to a v8. The engine, radiator, shocks, and front springs were changed. I have the rearend from a 67 gt. The front is still four lug, which I will most likely change in the future. I am not racing, draging or anything like that. Just a cruiser and a semi-daily driver. Any tips on the best ways to remove the rearend (by myself, yikes!!!) Thanks guys.:SNSign:

p.s. I still feel like a noob!

Jack the back of the car, put it on jackstands, and support the center section of the differential with a jack. Disconnect the rubber brake line, E-brake cables, differential vent, and driveshaft. After that, unbolt the back of the leaf springs and disconnect the U-bolts that hold them onto the axle. Lower the rear end and pull it out from under the car.

I've played this game several times.

A 66' 6 cylinder driveshaft will normally be a smaller diameter than a V8 driveshaft. The U joint is also quite a bit smaller and there is no readily available U joint to do a conversion to the larger V8 rear end yoke. So, plan on getting a V8 drive shaft when swapping the rear.

One from a 65'-70' Stang with the similar sized rear will fit. If you install an 8" rear, get one for an 8". If you install a 9", you would want a driveshaft from a 351 or larger car.

Breaker bar

Invest in a breaker bar if you are going to change your own rearend. BEST TOOL for those stubborn, rusted, siezed, 40 year old U-bolt nuts (or a torch).
