Bolt in rear end b

[565bbchevy]

If I'm going to spend that kind of money in a fabd up rear i would definitely save a penny and have my friend build me another Dana 60.
Just didnt know if there were other options than the 8.5 out there that are bolt in as they are becoming elusive.

The only true "bolt in" factory option would be the 8.5" rear from a Gbody, older A-body rear ends can bolt in using specialty rear control arms but all of them are wider than a Gbody rear so now you are also buying different rims with more backspace so the wheels don't stick out.
If you can get a deal on a Dana 60 then I would go that route.

I am leaning toward the ford 9" kit. Bolt in with lots of options. Set up. Easy to convert to rear disc.

I have said before the 9" is like the SBC of rear ends with it's aftermarket support.

I ran some numbers and when you factor it ALL in it is reasonably priced. You can prepare the rear end before installation. The pre-load, ring and pinion are set. New axles, drums etc and it takes away a lot of intangibles with adding the most important element of "cool"

another factor is the time frame, if you need something right now then a 9" is probably the way to go. If you have time to look around then there are more options open. The A body rear from 64 to 67 is 2.5" wider than a G body. It took me almost a year to find the 8.2" rear from a 64 to 67 Chevelle I was looking for. The 8.2" rear end I got was pretty must a bolt in with the conversion arms I got but before I installed it I took the 38 year old rear end apart and changed the parts that needed changing. That took a few weeks to source out the parts and waited till they were delivered. You won't have those issues with a "new" 9" that has been converted for a G body.

Pontiacgp and all the Canadians on the forum we are planning a trip to where my family is from this summer. Nova Scotia. Can't wait as I was a young boy when I was up there last. Fly into Portland then driving up to see the sights. One mission is to count the G-bodys I see and snap a pic if possible.
You can order the 9" wider if you want and I am leaning to add maybe 2"

I ordered mine 1" wider overall to accommodate my ARE rims I had on the car at the time but later could not use them when I went with a larger engine because I needed a frontrunner to clear my exhaust.

with the 2.5" wider rear on my GP the rims are 4.5" BS and I'm using 245-50-17 tires. The wide rear end gives the GP more stability in the corner, with the stock with rear end you can get a wider stance play playing with the BS but the less backspace the more pressure on the axle at the bearing. We broke the axles on the 7.5" rear on our circle track cars from the extra pressure in the corner with a small BS on the right rear of the car. We even broke a Strange axle for a 28 spline rear, the Strange axle was a drag axle and not a circle track axle. We were not aware of that until we sent the axle back to Strange for a warranty

I have stock rallye 15 x 8" rims with BFG 245/60r-15 and had to put a spacer to eliminate some rub. I really like the idea of the handling and I intend to work on that so a great mention. If you think about it is only 1 1/4" on each side. I won't be doing circle track though🙂

I know this won't be a cost effective idea, but would it be possible to remove the axle tubes from a 7.5 & use a '64-'72 10 or 12 bolt center? Knowing that it would still need the upper adapter arms. There would most likely be more cons than pros on this idea but if possible it could be an idea dispite a 9" would end up cheaper in the end.
