Iv converted From na to tt but retained the old clutch and flywheel with the na gear box, I'm now fitting a tt clutch and flywheel with my NA gear box, I'm aware it will need grinding out and the starter will need shimming out.

 

There was an Image posted by someone that specifically discribed where I needed to grind, I have a bad back and constantly repositioning it whilst it's up in the air will ruin my spine, will be doing it tomorrow so any help will be greatly appreciated.

it's not always neccessary to grind...actually I have found most NA transmissions will fit without any grinding.

You won't know until you will test-fit it.

 

You do need to shim the starter though.

 

If you insist on grinding, the area that's most likely to hit the ring-gear is the area on the inside of the bellhousing where the starter sits.

This is my thread from last year, I took a picture of the grinding out on page 3, hope that helps, I will try and find the other pic that is floating about.

Thanks guys! Done and dusted, it can finally handle the power now :)
