- 1970 Buick Skylark
Hello everyone! I own a 1970 Buick Skylark custom and I am looking to improve my 0-60 times, so I decided that I want to change out my car's rear end. The problem is, I am a college student with a budget (preferably $700 or below). I specifically want to run 4.10 or 4.11 gears. How would I go about finding an aftermarket rear end with these ratios? If a newer aftermarket differential is hard to come by for around the price I am hoping for, which truck rear ends would work that I could probably find at a local junkyard? Is it even worth it to buy a junkyard differential? And how will I make sure it will fit my Skylark?
