1. Radius entire chassis.
2. Open up chassis mount holes slightly and trim away lip.
3. Replace magnets with sheet lead.
4. Install MT-1 motor. Kept original pinion.
5. ScaleAuto guide with B-Nova adapter.
6. Paul Gage tires.
7. Heat and serve...

Pretty smooth all around. I like fitting some slightly wider tires that still look scale enough from the sides.

Fits in perfect in the classic series. Lot of fun tuning these little classics and now to enjoy some trigger time until all the kids arrive. :auto-checkeredflag:
