Re: [AMC-list] AMC twin grip posi question interchange

[markprice242 <wrambler242@xxxxxxxxxxx>]

I've got a twingrip 65 rear amc 20. I believe it is 3:15 ratio. I have not torn it down. What I hear is, 1. the early carriers are better? T or False? 2. something happened with bolt sizes? T or False. 3. the early carriers are worth more? T or False? Part B: How much if 3 is true? ----- Original Message -----
