Thanks Hal. Yes it the cup that is hard to find, a lotus parts supplier in Australia sells the lower balls.

I can work around it but interested in Grahams solution if/when its completed.

This is an interesting thread. I have a +2 with a suspect standard chassis and a type 9 gearbox with extended lever.

I was looking for a Spyder chassis but it seems like I had better go with a standard one unless the Spyder one is the later type, which unless I get a new one it will not be.

This simplifies my life somewhat as its quite a lot easier to find secondhand standard chassis. Mind you I still fancy a Spyder one. So many speed humps in my area.

All the best

Anyone suggested MT75 yet, it's been done and Zetec cars usually use it,

Was wondering about that as well.

The pics from the Spyder site posted above actually show the MT75. Might not be obvious, but the right side of the Spyder frame also has a little variation if an MT75 is being fitted. One of the diagonal braces has to be slightly wider to accommodate the starter motor. Unfortunately my chassis was shipped without this. I ‘field modified’ mine by cutting the brace and firmly bolting on an externally mounted flat brace. Not sure this could be done with the body in place.

There is also a second major variant with the Spyder chassis. For Zetec compatibility the front tube/vacuum tank needs to have a half moon shaped cutout. This obviously cannot be easily accomplished afterward. Not a big deal if sticking with your Twin Cam. If looking at available chassis, or even if ordering a new one, might want to get this variant. Be careful they don’t change something at the transmission mount though!
