Bud,
I restored my TR4A frame back in 2004.
>From what I remember of my research, because the TR6 engine is longer...
1. The engine mounts are more forward
2. Meaning the steering mounts are also
3. The TR6 also has slightly different mounting for the lower, front
suspension arms, having two bolt holes instead of just one..
Maybe Ratco developed their chassis with elongated engine mount points with
multiple holes to suit the TR4A or TR6?
