Driving Project 69 Chevelle L78

Can I fit a 275 60 R 15 under the quarters on a 69 Chevelle? Right now the car has old 255's on all four corners.

Thanks

Absolutely..although the backspacing on your rims is what's really important.
I run this same tire on the back of my '70 with a 4-1/2" backspaced rim with no problem.

I should had been more descriptive. I am using the typical 15x 7 Rawlley wheel. Not sure of the backspace g on this wheel.

If it's got the usual 3-1/4" backspacing,you might in jeopardy of hitting the top of the wheel moulding mounting lip.

The typical 70s monte carlo common rally wheel has a 4.25" backspace (1/4" offset).

That is what is on the car the FW coded wheels.
Should I stick with the 255's with this setup?

The car has a 67 Muncie in place with no speedometer cable installed. Can I put a 67 Chevelle speedo cable in place and it fit? A 67 speedo location is on the driver side and a 69 on the passenger side of the transmission.
Thanks

I cleaned the ole Chevelle up today, pulled the seat belts from under the back seat and installed the front belts. The rear belts should had been soaked in a bucket of oxy clean but that is for the guy that restored this ole girl. I drove the car 8.5 miles and it drove ok. Tightened up the steering box drives much better but the tires are shot.

FWIW on the broadcast sheet the wheels show as YA's with 52 Paint and no stripe...

Other 69 broadcasts I have seen do not have a body color in the wheel box when YA's are indicated.

I have been racking up the miles on this car. Really fun to drive, and different driving experience with the full frame as compared to the uni-body cars. I still have not pulled the rear end cover but I believe I have changed my mind now that I have put over 100 miles on the car. I believe the 3.31 gears are in the car. The engine just does not seem to be revving that high at 60 mph like it should if it had 4.10 gears in it?
