O.K. I dont know what to do. I can get a 205 and it will bolt up to the np435 no problem, but the gear ratio is like 1.96:1. Is going the easy route and saving about $600.00 worth the lose is crawling speed. The np435 is way low in 1st, so will I gain back some of that low crawl speed? I really like the 231 thats in the jeep now, but I need to upgrade my tranny for the engine I got, and this sounds eaier to do.
