1. If you do Not have the adjustable chassis the replacement is: Slot.it SICS08T-60B Lancia LC2 Chassis EVO6, https://www.professormotor.com/product-p/sics08t-60b.htm
2. F30s are easy to find and *if needed* buy some from a club member (I have some spares as do most members). In lieu of cash, trade them the ones you ordered when they arrive, no need to wait on the shipment. Ditto for other common parts such as the deep wood guide Slot.it SICH07 and braid.
