And you’ve just highlighted one very big reason that the P-30 disc conversion isn’t a good solution for many of us. It’s great if you have a later model advanced design big bolt with the 5.25center circle, but it’s not a good solution at all for the earlier big bolts with the 4.75 circle. If I went with the P-30 solution in my 1940 1.5 ton I’d end up with 19.5 radials in the front and 20 inch bias ply dually in the back. So for many of us swapping spindles isn’t such a simple solution as the old thread makes it out to be.
Yet the ten year old thread with 15 plus pages and 240,000 views peddles this “solution” as a solution for all big bolts... it’s not. That’s all I’m saying. It’s time to split the solutions to what works for the early vs AD trucks... not just peddle one single solution for one set of trucks as a solution for all 1.5 ton trucks. The alternative is we just split the entire big bolt forum into early and a late sub forums.
