Cool 308 chevy rearend

I keep hearing (from my rodder buddies in town)that I may have more trouble putting the 308 in my 37 chevy coupe than I want to deal with.And how the Ford nine inch would be a smarter way to go.I have seen many 37 chevy's in mags. using this rearend and I would really like to keep the chevy theme throughout this project right down to the bow-tie gauges on the dash. the rearend measures 59 inches in length, and what about the original spring plates will they match up or do they get cut off. Spring is getting closer and I hope to get started with this project soon and I want to start with the rearend, so if any of you guys can help let me know. Thanks NORM...

norm I have talked to you a number of times. I know you are not building a race car. There is nothing wrong with the chev rear end. Think of how many Hi perf GM cars used that rear end. your buddies just think you have to much money and want you to spend some.Cut the pads of the old rear end and weld them to the new rear end. Just make sure the angle is right before you weld it up tight. ROY

I agree with Roy that for street use the Chevy rear end with a 3:08 should hold up fine.
I do have a concern over the 59" rear end however.
My old Chevy rear end measured 55" from inside hub flange to inside hub flange and was a tight fit in my 38 Chevy using 15"X 7" wheels. My spring perches measured 45" center to center on the rear end tubes.
I have since gone to a Ford 9" cut down to 53" with 3:70 gears because I went to a 500 ft lb torque engine but the old Chevy 10 bolt did just fine with my 300 hp sb Chevy.

You should always consider rim backspacing when trying to determine rearend width. You don't need to actually have them in your possession, but you should have something picked out and know what backsets are available for that rim.

and its alot less painful to just buy new spring perches from summit for 13 bux than it is to cut them off the old rear end.
