thanks guys. so if its an inch wider - in practical terms my back tires would stick out an inch? and if I understand backspacing correctly (which may not be the case) i would need to get new rims with different backspacing to put tires back to original?

One half inch per side - one inch overall width increase of the rear end assembly.
If you have some room on the outside as in more than 1/2” then your current wheels should work. |

There should be two letters followed by 4 numbers followed by a single letter stamped into the axle tube. I think a 3.73 rear should be a K5 code for posi and K4 for non.

It’ll fit in a 64 GTO, took one out of a 70 GTO and put it in my 64 GTO yes about 1” wider. Still was able to get a 11” slick on.

Definately no expert here, but will rear end that takes a 3.73 take a 5.13 gear as well? I thought that a 3 series took the 308 and 373s and 4 series took 4.11s and such. 5 series for the 5.13 and so on.

They are GM gears so I'm going to say yes. They are thick so it might even have a 3 series. I'm sure the experts will correct me if I'm wrong

It's all about the rim backspacing. I currently run 245/50/17's, but have run 255/60/15's also. The 15's were on 15x7's with 4.25" BS. The 17's are on 17x7's with 4.625" BS |
