Thanks John, that is a good idea. It just requires knowing a rebuilder that is trust worthy
The 1 1/4" that I thought might work is a 98 Dodge Ram 3500 IIRC. Only concern is that it's for PB, and the hole for the pushrod might be too shallow.
That bolt pattern is slightly different, but the bolt holes can be massaged.

As said, I will want to test pressures at all wheels and MC before deciding to switch.

Thanks,
Ran
