FJ flywheel thickness?

[FJ510]

anyone know what the original thickness of a FJ20DET (DR30 Skyline) flywheel is?   also, has anybody had clutch issues before where they were supplied a clutch plate that fit perfectly but when taken out found the plate had carved into the flywheel bolts as in being too tall in the centre (spring) section?   speaking of which, anyone got any prices of a decent brass button plate? in perth it will set me back $263 + GST just for the plate.   and last but not least... if i have a h/duty pressure plate only a few hundred k's old and i had my flywheel machined, would it be alright to throw in a button plate?     cheers   ryan   --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
