Okay, so i tweaked my Christmas gift Sideways Stealth black Lambo with guide spacers with excellent results - better smoothness and quietness. But as I tweaked the rear, I broke the axle bushing support such that it was laying-over. I re-glued it with CA and made and a notched wooden strut support to help retain the plastic bearing support. Looked good, but the pinion/gear mesh was tight and restricting. I couldn't easily remove the inside motor screw since it impinged on the bearing support to make adjustments and wound up breaking everything irreparably.
So: 1) is there a reasonably idiot proof way to make, align and glue-in a new bearing support, or 2) is there a replacement chassis available, or 3) should I just shelve this awesome looking stealth Lambo?
