Flat o matic.

[scooder]

I have here a flat o matic kit, came out of a car that's having a brand X monkey motion thing slapped in it. Now I didn't remove it, the bloke putting the wrong engine in did, I have the torque converter, bell housing and flex plate (not sure if you guys call it a flex plate, if not it's the chap with the starter ring around its edge), I've read the flatomatic installation stuff and it mentions a spacer that may be needed twix the crank flange and flex plate, anybody know the thickness of said spacer? I can then make him up ready for if I need it.
Many thanks,
Martin.
