Is there a ring & pinion or center section swap to have a more highway friendly ride or would it have to be a whole axle swap? Also what were the gear choices in the C20's? It also has the 16" split rims, are there a particular set of 8 lugs I should be looking for? I dont want to go real wide. Thanks

Wheels are easy. 8.lug with a standard offset. Actually any of the big 3 wheels will fit I think.

Those gears are not being produced new by anyone, and OEM is extremely scarce and pricey. The usual ratio for a stick shift C20 is a 4.56. There's a Dana type 60 8 lug rear that was used by GMC that's also pretty scarce, but there are all sorts of aftermarket ratios available for that one. I've got one of them under a 59 Suburban with a 3.73 gearset for a Ford, in a GMC housing.

"Hotrod Lincoln" just spoke to a guy today who has one of the 4.10 center sections available, I'll have to see tomorrow what he'll want for it. On a side note I have a friend who has a Brownie OD auxiliary box available, that could be an interesting alternative. | | | | | Joined: Nov 2007 Posts: 128 'Bolter | | 'Bolter Joined: Nov 2007 Posts: 128 | The guy I mentioned previous has the complete 4.10 rearend from a '72 for $500, is that good, bad or average priced? | | | | | Joined: Feb 2004 Posts: 29,878 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,878 | If you don't want it at that price, I'll be glad to come and get it! Be sure to give him a big wet kiss when you pick it up! Can you post a pic of the Brownie? I might want to make an offer on that, if it's the right size for a medium duty truck.

The aux box is a Spicer 3spd, OD/Direct/UD, about the size of an SM420. Not sure how to post photos.
