If you are going for the 35s and wheelin go for the 4.88s if stayin with the 33s go for the 4.56s. Better too much gear than not enough.

Re: 456 or 488\'s

I presently have 4.56's w/33" tires on my Jeepster. I turn about 3000 rpm at 65 mph in drive. I would not go with the 4.88's w/33's if you will do any highway driving, but would do 4.88's if you go with 35's. My 700R4 tranny has 30% overdrive, so this brings my 65 mph rpm down to 2100, which is a little anemic. I will probably switch to 5.38's to bring it back up to 2500 rpm.

I have 35's on my 78 and went with the 4.56. It pulls about 3 grand on the highway with my TH400 and D18 tcase. It does a good job pulling my camper and it responds real well off road. I think this is the way you want to go.
