Following similar threads on P-30 and other disc brake threads. Finally solved my problem on recent acquisition on GMC 370. Had planned on finding P-30 front spindles. Thought about recently introduced Series 400 Saginaw power steering box. However, upon inspection of truck and Cummins 5.9, it turned out starter cannot be easily inserted with steering box in place.
Turns out GMC 3500 HD(not a P) axle would would work fine with the exception of mounting steering box outside the frame, like earlier 4wd and std. older front axles.
So will be able to mount this axle with an outside the frame port and starboard swinging power steering Saginaw box. Axle came without steering box.
Look around, you mount find one too.
Next comes the issue of wheels. 22.5’s look correct for this series truck, however they have been out of production and 19.5’s look undernourished in the wheel well. Some have had some made however at almost $400. each plus long lead time, they are tough to swallow. If we could put together an order of say 50 or 100, perhaps we could reduce the price and get a lot of our trucks going again.
Speak-up if any interest!

Ed I’ve often thought of the 3500Hd front axle but it seems a bit wide for early trucks such as my 1940. Curious to know the track width.
