Re: [oletrucks] New gears for highway speed in 54 3/4 ton

["Bobby D Keeland" <bob_keeland@usgs.gov>]

Anyone know if the 1962 3:90 will fit in a 54 3/4 ton rear?  Also, with a
4:10 (or 3:90 if possible) rearend and 283 v-8, what "manual" transmission
would be good for highway speeds (65-70 without overrevving the engine)?
Any suggestions appreciated if they are at least helpful or funny.

FYI some 1962s have a 3:90 ratio don't know if the 3rd member will fit up
but maybe someone else will know.
