didn't 1951 chevy 3/4 ton come with a 4.57 rear end?
I have not removed the 51 pig yet hoped the 68 would give me highway speed without high rpms
what year pig pumpkin do I need for 3.90 or low 4.00 ratios? Or am I going the wrong way should I be looking for 3.00s or 5.00s ratios? thanks Bill
Bill 1951 3/4 ton 5 window pick up
