Hotshot Modified Chassis

[Tobamory]

Guys does anybody know if you can buy a modified chassis for the Hotshot/Hotshot 2

In the 80s I had the original and bought from Morley Models in Leeds some fibre Glass affair, that worked really well.

Ive seen a great Youtube of a guy whos modded one, but I feel this is some engineering thing the guys done himself.

I just wondered if there was anything still about that you can use.
thanks
