I'd trade you mine for a d60. Seriously unless you're dead set on one and plan on smallish tires don't waste your time. I regret mine but have to much in it to start over.
I've got a one out of a 78 F250. High pinion with 4:10 r&p. Complete drop out. Also have a complete Sky Manufacturing solid axle swap kit for 89-98/99 full size Chevrolet with front arch springs. I'm in London Ky
