I wouldn't start a Pro Street car with the stock 7.5" 10-Bolt rear. The 7.5" will be fine if you have no traction. Wide sticky tires will kill it quick. You need a 9" Ford, 12-Bolt GM etc..

Nice website thanx for the link,if I bought there hole set up what else would I need?

[SSedan64]

If you bought a complete Rear you would need a conversion U-joint to connect it to the Driveshaft depending on which series Yoke the Rear comes with. Depending on how much HP/TQ your engine will have you may need a stronger Driveshaft.
Upgrading the upper & lower Control Arms to stronger aftermarket ones with Poly bushings would help also. Adjustable Uppers will help to set your Pinion angle. Don't get the kind with Heim joints unless it's a Drag only car. They'll transfer too much vibration from the rear to the car.

Ill need a locker&gears,I didn't see a package that included them.Is there a book I could buy that would help?

[SSedan64]

May find a book on Amazon etc..
This link has the Center sections>> http://www.quickperformance.com/Prod...20sections.htm
Other parts>> http://www.quickperformance.com/Products/rearends.htm
A complete Rear will be cheaper than buying individual parts. You'll have to contact them for pricing as there're so many combinations, Diffs, Gears, Axles, Brakes etc..

[SSedan64]

Cheapest option would be a 8.8" Ford Rear from a Mustang. Fords version of a GM 12-Bolt.

What type of suspension are you going to use? Moser has complete Dana 60 rear ends that are cheaper than the 12 bolt or 9 inch, and stronger. You can add brackets for ladder bars or 4 link. You can get these any width you want with any gears and several differential choices. They also have 35 spline axles.

The first thing you need to do is get the wheels and tires that you will be running so that you can figure the total width of the rear end. Also remember that the pinion is offset 1/2 inch to the right on GM cars.

I like the mustang rear end option,Ill get the book too,I wouldn't even say that I know little about rear ends because I know absolutely zero!I'm gonna go real slow&read all I can everywhere I can.I'm hoping I can figure it out.

[cutthroatkid]

No haven't considered the suspension yet,not even sure where to start.I'm planning on driving this thing once in awhile&going to the track once or twice a month.Too expensive too drive this car much,since the new motor it only gets about 9-11 miles a gallon.As far as wheels go right now I have a set of z28 rims on there but I've also got a set of cragars,I wanna put on a set of pro mags or something similar,

The only probem that I know of with the Mustang rear end is that the axle tubes are smaller. They don't have 3 inch axle tubes like other rear ends do. If you want to use the 8.8 rear end then you might want to use a truck housing.

[cutthroatkid]

Ok its been storming allday so I just been reading up on the 8.8 swap&can't find really info on if I'm gonna have To mode the driveshaft,yoke etc

[SSedan64]

Gonna have to keep reading. I'm not sure about the length compared to the 7.5". May need the Driveshaft shortened & a Conversion U-joint or change the rear of the DS to fit the 8.8" or use the Stang DS and add the front GM Trans Yoke.
One thread I read said they were going to remove the axle tubes from the 7.5" & install them into the 8.8" center housing. Instead of swapping all the brackets from 7.5" to 8.8", Spring & Lower control arm mounts.
Another said you can buy these setup for the G-body on Ebay etc.. I think J.D.Race (monzaz) on the MalibuRacing site does them also.
