What I can do to help you.
Hi David, Sorry about the post getting astray there.
I am looking through my box of extra items, I have some extra sets of wheels, a couple of motor mounts, some extra fuel tanks, some rubber bands, some older style hinge slotting tools, maybe an extra fuel pump, not sure yet, some fuel tubing, and a few other odds and ends. Sorry I don't have any old kits or engines to give away. I will put a small package together with enough hardware to complete a trainer and send it to you, please email me your mailing address and I will see what I can do.
Now, can anybody else contribute to the cause??? lets see if we can help keep the hobby going for him.
