That's the one.
Uses a GT6 rear end and a Spitfire front end welded to a box section 4x2 ladder style chassis.
Overall it a good idea but it looks like it's been through a few hands before coming to me so needs a fair bit of sorting out.
Fitted a 2.5 six cylinder engine, left over from Mighty Nimrod's build.
Re-styled the back end.
Now looking for a suitable fuel tank and a set of bigger wheels.
