Hi all. New to forum old at r/c. I have an NMT2 with 18SS, THS pipe, MS filter and other mods. I stripped the rear diff gears even after shimming. Bought the steel gears from TOWER, but they do not have the pins that hold the spider cross shaft in place. put it together anyway, and now it turns rough and locks up. what can I do what parts do I need? Great truck, great engine want to run it bad. Very good forum. Thanks for your help.
I toyed with the notion of building what you have at length... I'm sure it's a blast....

Look in the HPI manual (if you don't have it, they have all manuals on their site) for the HPI part#, look for a Master blow-up and the number it carries will match with the part# on a list. Once you have it you can plug it into Tower's search. I don't know what it is, but you can search for a string like
hpi gear and get 50 results. The gear you need invaribly will not turn up. If they don't stock it they can order it if you call them with the HPI part #. Your local hobby shop can also order it.
