Welcome to the bizarre world of car modification, you haven't even scratched the surface yet. Wait till you progress to axle diameters/wheel/tyre sizes/compounds/gearing ratios etc.

There is a complete lack of standardisation across the many manufacturers and millions of possible combinations so it's virtually impossible for anybody to produce a complete chart of what part fits which other part. Sticking to a single manufacturers' parts is a sensible way to begin though.

That is what forums are for - ask and you shall receive. Pendle slot racing are also a mine of information, a phone call to them about the compatibility of something you are considering is well worth while.

Eventually you will manage to build up your own database of knowledge and be able to help other people. In the meantime, have fun and experiment.

Many thanks for your help!!!
Will go smooth on that.
