Pressure plate fouls the end of the transmission so the box doesn't quite bolt up. It's taller than stock but was hopeful it would fit anyway. It's really close, like 5-7mm, but it's enough to screw to whole fitment.
So I went with using the stock pressure plate and machining 1mm off the flywheel edge to increase clamp load. But there have been other delays now with getting the flywheel machined and subframe not ready until tomorrow, and wiring being a big headache, so I will put the whole thing on hold now until I can source a new pressure plate (I think I have already).
Bright side is it'll make it easier to fit the other mods that haven't arrived from the US yet. I still hope to head down the strip before the season is out.
