Thread: Camaro rear end for 1941 chevy coupe

Tweet

Should work out about right on the track width. Don't know about the spring mounts lining up. Move the diff with springs attached into place and see how everything lines up. Are the '41 springs still valid? If so, you may want to use them and simply locate the Camaro diff in place and use new weld-on pads to use the Camaro diff with the '41 springs.....

Bolt the '41 springs into place. Bolt the pads to the springs. Bring the diff up to the pads and tack weld them in place. Disassemble the diff from the springs. Finish welding the pads to the diff, heating the diff tube all the way around with a torch everywhere there is no weld to prevent tweaking the axle tubes and mis-aligning the bearings and seals in the ends of the axle tubes. I'm not sure I'm making this clear. The weld on the spring pads will only amount to about 1/3 of the circumference of the axle tubes. Use an oxy-acetylene torch to add heat to the other 2/3 of the axle tubes to equalize the heat and minimize resultant warpage of the tubes.

With weight on the car, at ride height, I'd put an angle finder on the rear face of the TH350 housing to determine the down angle of the transmission. If you leveled the carburetor pad on the intake manifold, the trans is probably at about 3 degrees down bubble. With a leaf spring rear suspension, the pinion will climb the ring gear more easily than it could with a more solid suspension system, like a triangulated 4-bar for instance. Therefore, I would install the pinion in the car at zero to one degree up bubble. With light power on at cruise, the pinion should climb the ring gear at about 2-3 degrees and the angles will cancel out, providing a smooth transferance of power.

For a driveshaft, have the car on the ground at ride height or sitting on a drive-on lift so that you can get under the car with the suspension loaded. Insert a yoke onto the TH350 output shaft and push it in as far as it will go. Now, pull it out 3/4". Now, measure from the centerline of the trans yoke to the centerline of the pinion yoke. That will be the dimension you will give to the shop that will make your driveshaft.
