Right, I’ve completed the front sections of my McSorley 7+4 chassis and now need to decide what mods (if any) are necessary at the rear to accept a Rorty type DeDion assemble.

I’ve cot a copy of the GTS drawing showing mods to a standard chassis. Is this the best way to go?

John.

I used alterations along the lines of the GTS plans, although I added some additional bracing.
Apart from that you will need a couple of diff brackets and that should be about it.

Cheers

Alex
PS
Remember to allow for the extra width of your chassis on to the drawings
