because of transmission failure
The Pontiac LeMans would be my choice. It is slightly larger and more luxurious. The Pontiac engine was also a better engine than the Chevy.
in a shop!
24-inch rims will indeed fit on a 1973 Pontiac LeMans. The tires would have to be closer to low profile model, however.
Might just need a front end alignment or maybe balance and rotate your tires.
It's pretty much a bolt-in. Would require correct motor mounts, of course. The holes may already be drilled in the frame.
The 455 and 400 was an option motor in the 1972 Pontiac LeMans, yes it will fit. I'm not sure if a beefier tranny was also included?
Leaking valve cover gaskets would leak onto the exhaust pipes under the hood of the car.
fuel filter stopped up or fuel pump loosing fire.
That would depend on a multitude of variables. First...which engine...350, 400, 455. How do you drive it? Is it "built"? Stock....I'd say around 12-15 average. I've built some that would get close to 20 and others that did good to get 8.
sounds like a motor mount is broken or a transmition mount. have those checked.
Depending on what body parts you are needing, the 70-72 should fit. This would include the GTO and the LeMans.
Yes if it had one, however it uses a pick up coil inside the distributer
