Hi so I’ve been moving my MTXL parts over tot he RCMax billet chassis but I’m having some issues getting everything to line up properly without the cut in the chassis. I can shim the center diff area enough to get it working but when I add my fid center diff setup it’s all just a bit short and needs more shimming, what ends up happening is I’ve shimmed so high that I can no longer get the brake pins to slide into their holes to apply the brakes, not enough of the home is showing to get the brake stems in. So,I’ve been kicking around the idea of changing my spur to something smaller then the stock 67. I knelt he dbxl has a 48 and a 50 the t I think would work as I know the vehicles are close tot he same but I was hoping to get a bit closer to the stock size so it more low end still and notice you can get a 5ive in a 57 or 58 which I think the size diff would be enough to let me clear my chassis without shims and everything would work. My thoughts and questions are, are spur gears pretty much interchangeable? If I change the. Spur must i change the pinion? Thoughts? I’m talking about about 4-6 mm shim up to get clearance from the chassis so the spur doesn’t need to be a lot smaller, I don’t think? Thanks regardless guys
