Here's one for you smart Camaro guys!

I purchased a 34 chevy with a Camaro rear end #BS1011G2 3894860 which I think is a 68 12 bolt with a Eaton posi and 3:31 gears. Here's the rub! From the center yoke to the drivers side backing plate is 27 3/4" and from the same yoke to the passange back plate is 27" THAT CAN'T BE RIGHT! How am I supposed align the thing on center??? Thinking I may need a new rear end. There goes another $3000.00 Thanks for letting me vent.

You don't have to have the pinion lined up to "center". As long as the imaginary center line of the engine and trans (crankshaft thru trans output shaft) heads straight back, you could have the pinion a number of inches off center and it wouldn't matter. What's important is pinion angle (the angle relationship between front and rear u-joints), both horizontally and vertically. Driveshaft angle isn't an issue if pinion angle is right. As an example, on a big block Camaro, the engine mounts are different to rock/move the engine over to the passenger side to give more clearance on the drivers side, and the transmission crossmember mount is also off center to move the tail of the trans over to the passenger side which keeps the engine line straight back. The engine is sitting in the car off center, but it doesn't matter. Read this: Setting Pinion Angle

 

thanks for the good info..I got schooled, again. But, is it true or did someone modify this rear end?

 

I have a 9" in the rear, so I can't say, don't have a stock one to measure against!

 

The factory Camaro rear end is produced with a 1/2" offset.

 

Thanks DeereMan, But what do they do with that offset? Do they angle the driveshaft between the tranny and the differential yoke or do they bring the driveshaft square and shim the one rear wheel 1/2?
