Hey all,
I ran through the archives and didn't see this answered:

Going from an original 8.2" rear in '69 Camaro with TH350 to an original 8.5" rear from '73 Nova. I have a new driveshaft that fit with the TH350/8.2" rear. Will it fit the same with the Nova rearend?

Thanks!

Joe,

I recall some post where it was shortend 1" and others where it worked with the same length. The overall opinion was to wait and see what you needed after the 8.5 is in.

I'm going to find out soon myself. I brought home my 75 Nova rearend this weekend. The guy that set it up said I didn't need to shorten the drive shaft or change U joints. I was under the impression you had to. We'll see. Keep us posted here when you do yours.

Thanks Robert. It would suck to have a brand new shaft hacked up.

I would think the U-joints would be the same Winch. No biggy there anyway.... they're cheap!

Well I hope your luck is better than mine. I just put a Nova 8.5 in my '69 and went to check the driveshaft fit. The driveshaft was in the trunk when I bought the car so I just assumed it was the original one. Low and behold, the damn thing is 2" short. Go figure. Everyone else's was either OK or too long. Could this be a driveshaft for a manual transmission or is it just from the wrong car?

If you have a 12bolt driveshaft they should be the same if you have an 8.2 everyone I have ever done the driveshaft was too long.

Well, I bought the car with a TH350 hooked up to a 400ci and the 8.2" rear in it. The driveshaft was made new to fit this combo, so I'm hoping it'll fit right back in with the 8.5" rear swap. I'm keeping the TH350.

I had to shorten mine 3/4". Like someone suggested above, just wait until you are ready to hook it up so you'll know for sure.

When I swapped my 68 manual 3sp,single leaf rear, into a 73 Nova TH350 the drive shaft bolted right up!
Hope this helps.
I haven't bolted up the Nova rear yet,the bolts are just started (so I can push the car around) she's in tear down mode.

Mine was out of a 72, and the Front and rear U-joints were the same as my 8.2, but I did need to shorten by 1/2 - 3/4 of an inch (can't remember the length.)

I THINK in 73(or 74) they went up to larger sized U-joints.

Now that you guys are talking about Nova rears, I asked a while ago about a narrow diff for my 67 Camaro & got a cloudy answer. Can someone give me the real facts on what year/width/size etc will work, thanks, Mike.

i have a 8.5 sitting on the ground behind my 63 nova. had a chance to measure the two. seems that the pearches are in the same area, but the 71-71 tubes are longer. they should bolt up to the 67-69 camaros. i will need to shorten mine for my nova....like 1" each side... enough for my 15x8", 205/50/15's to stick out... yuck....

Any Nova rear up to '76 (and maybe later, but I'm not sure) will bolt right into '67-'69 Camaros without any modifications.
