These 0.020 under bearings fit A65 through 0200 engines.  They could be A4 (with locating dowel), A5 (with locating notch), or A6 (with offset tabs).  Your case may require modification to use this bearing set. The flange bearing is removed per the STC. Please advise our Sales Dept. of your crank case set up.  Our sales staff will assist you in determining which one of the three style thrust-washers is right for your engine.

A4 style (with locating dowel) uses (2) A36074 and (2) 36075 thrust-washers 

A5 style (with locating notch) uses (4) 35552 thrust-washers
