Summit Legend 5 on a 69
 

These look like the only wheels that I can afford at this time.
So I am looking at purchasing the 142's but not sure BS will work?
The 18's are 8.5 wide/ 5.125 BS (front) and 9.5 wide/ 5.75 BS (rear).

Have 1.5 lowering springs and C5 brakes F & R, lips are not rolled.

Thanks for any help, Gary

I purchased the same size for the front on my nova, still waiting for them to get here to say how well they fit and i went with 6 inches of backspacing on the rear 9.5's but nova's need a tad more backspacing so i think you will be fine.

i'm in the market for some wheels for my 70 nova right now. Post some pictures of your car with the new wheels when you get them mounted.
