I was thinking of boxing the frame but once I found out that the 4bt is really only about 100 lbs heavier than the stock 235, I wasn't really worried about it. You still think its necessary? I might just end up boxing it anyways since I really enjoy welding
You are probably right on the GM 10 bolt. I'm sure that 12 bolts are pretty easy to find too so ill probably just go with one of those. Wont need to re drill the hubs since I'm not going to keep the stock wheels. I'm not certain, but since ill be going with 4-wheel disc brakes, I'm betting that the stock wheels wont fit.
