I have a 75 lasabre custom that im trying to put 3.73 gears in. The problem is the rearend was only fun for one yyear and no one can find gears for it. Any help anyone can provide would be great.
I think your car has the 9 3/8ths rear. You have the 350 or 455 engine? If you have a 350 your stock gear should be 3.08 455 should have a 2.56 The 3.08 is a good gear A 3.73 gear will really rev the engine on the highway too much without an overdrive trans.
I usually ignore posts with no info in title. If you want attention to your post, be specific in title. Like "Need help with gears in '75 LeSabre diff." Good luck...TJ55
