Ton of fun, I like alot of others here replaced my pumkin with one from a 70 chevy, 4:10 ratio. Does wonders, I an able to keep up with traffic with no problems.
Yes I do still haul with it and it still has plenty of power with those gears. It's a easy swap, did mine alone in about 6 hours, played withe the grandkids some during that time too. The hardest part is finding a doner.
Have you looked at this?
