Hey dudes, well I've got this question thats been buggin for quite some time.I have a 1965 half ton fleetside, well my question is what rear end ratios did these come with, or is there a easy way to find out.See I've just installed a Muncie M21 into it out of a 67' so,top speed is 50, 55 downhill that just aint cutting it for me and what will give me the freeway speeds I want, becuase vegas people are always in a hurry.
Thanks for all your help
