What rearend???? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

blazntn · 11-21-2011, 09:32 AM

I am need of a rearend for my 69! It will be layed out and bd to lay pinch welds.

I need to know what my best route would be. I am currently 6 lug but I am not against swapping to 5. I was wondering about the Caprices. I think I need something a little narrower than stock.

thanks

as far as what u need// need info on engine power you are planning a 200hp or 600hp engine will need differnt strengths to live// as far as width need info on rims with backspace etc

blazntn · 11-21-2011, 09:52 AM

Forgot about that. I have a mild 350, with a 700r4 behid it. This is going to be a cruiser not a racer. I was wonder about Caprices, Regal, S-10's. Anything I can pick up easily at a Pull-a-part.

andrewmp6 · 11-21-2011, 10:11 AM

the s10 and g body but for the grand national and 442 used a 7.5 10 bolt which is kinda weak.I would be looking for a 10 or 12 bolt from a truck you'll have to change the spring perches but that's not hard.

blazntn · 11-21-2011, 10:49 AM

what model trucks. I would like to find one that I will not have to narrow.

blazntn · 11-21-2011, 11:50 AM

Would a 73-87 rearend fit? or are they wider?

fishingjred73 · 11-21-2011, 07:05 PM

1 1/2" wider.......seems like, somebody else will confirm or not.

andrewmp6 · 11-22-2011, 01:35 AM

Do you have a rear end in the truck now?

blazntn · 11-22-2011, 08:05 AM

No, I do not have a rearend.

andrewmp6 · 11-23-2011, 02:48 AM

Does anyone know how wide the stock rear end is so he can have a idea what to look for?

blazntn · 11-23-2011, 08:12 AM

I believe stock width is 60.5" I am looking to something close to that. But strong enough to hold up to my motor. It isnt going to be a race car but I dont want it to take a dump on me at a stop light.

fishingjred73 · 11-23-2011, 10:39 AM

Here's some info on a 71 rear which is an 1 1/2" wider than the 70 down.

Don't overlook the 8.8" rear out of a Fox body Mustang....

Easy to find.
Used housings can be found already beefed up.
Strong ((falls between the 10 & 12 bolt in strength).
Huge aftermarket support.
Disc brake kits & 5-lug axles readily available.

mbgmike · 11-23-2011, 11:03 AM

HERE IS A USEFUL CHART
http://www.carnut.com/specs/rear.html
just for info we build rear ends to any width and any HP starting at $1000.00

andrewmp6 · 11-25-2011, 02:31 AM

Scoti the 8.8 from a explorer is used for a alot of swaps early mustangs and some jeeps.

True, but I recall the axle tubes are differing lengths & the overall width is wider vs. the Fox body stang. I think guys typically shorten the longer side to equal the shorter side for a cheap-ish alternative. I don't remember what the diff was in widths between the 2.

andrewmp6 · 11-26-2011, 01:55 AM

The explorer is wider then the mustangs like a inch or two but its 31 spline and most are a factory lsd too.They do have a off center diff which can be fixed like you said shorten the one side.

CC69Rat · 12-06-2011, 09:13 PM

67-68 is 55.5" plate to plate. Some early 69's
69-72 is 57" plate to plate.

or, the WMS measurement if you prefer.

Find an early rear end housing and you can run a wheel with .75" less Backspacing (looks wider / more lip)
