I didn't get my 09 in my 64 this year, but its waiting patiently, even though I'm not. ( patient, that is ) Any way, in the mean time, I'm looking to change the rear gears, in a spare pumpkin, that I have. What I found out was, there's not a very big selection for us 55-64 guys. Summit now has a 3:73 instead of a 3:70 and a 4:11. By summer gas will be $4.00 a gal. So I guess a 4:11 is out. I seem to have read somewhere that the 3:70 R&P was junk. Is the Richmond 3:73 a better choice? I think I'd be happy with a 3:55, but can only get them with a 25 spline pinion. That doesn't help us 17 spline guys. Not only are we truck motor lovers, we're splineless too. Skip
