Non cab forwards?
 

Are there any other shells that aren't cab super-forward that fit the K1 and SVR?
Does the SV2 body fit the SVR?

SV2 will fit the SVR, but Schumacher shells come pre-cut, so you will have a motor plate sized hole at the rear.

The word 'bollocks' comes to mind. Might text tom and see if they have any uncut proto's laying around :) Not very likely I guess - perhaps a nice option part for them to release?

Give it a bash, I had to fudge the rear mounting on my SV2 to fit the SVR shell on!!

Not sure if the SX3 will fit the K1?

A couple of the lads at out club had 511 shells fitting pretty well on the K1 while they were waiting for theirs to be painted!

I've run an SX3 shell on the K1.
Little bit of modding needed but fits fine enough to give a non cab forward shell option.

The SV shell might fit the SVR, but instead of having a gear cover shaped hole, you'd have a gear cover shape in lexan!!
