can anyone tell me if there are more then one flywheel for the xf 4.1 i know about the crankshaft bolt are two diff pattens but was woudering about 3speed and 4speed and t5 5speed boxs are the same flywheel

What do you mean by 2 different flywheel bolt patterns?
I know that there were at least 2 different clutch pressure plate bolt patterns...

on the left hand side of the eng there is a raisd number it is ever 84 or 86 this tell you that the crank is diffrent the 84 has it bolt for the flywheel more to the outside of crank but in the 86 they moved them more to the midle as they thorght that would fix the oil leak prolbem with that motor
