Like I said before, the ID tag on the front of my '72 K/20 Highlander read 4.09. The difference between that and the HO52's 4.10 doesn't make enough difference to matter and if it had a Dana 60 that would be 4.11. So the trucks care a lot less about this than we do  |
I've got a Dana 44 out there in the shop I'm rebuilding for a kid that has that same tag. Has 4:09 and the tooth counts on it, he's going to run that with a 14-bolt rear with a 4:11 in it...I learned the hard way a long time ago, it's better to run a tic tighter in the front than in the rear...
