I was wondering if anybody has had any luck finding frame sliders and swing arm spools for the old f1's?

 

As far as spools go, you can make you own. Here are some ideas:

and there are many discussions about drilling and welding them on. Just do a search on "spools"

For sliders, either find some universal ones or don't use them at all. Most are cheap and for show anyway being worthless and causing damage in a crash.
