3 8mm on the oil pump?
Bruce

Thanks Bruce

Maybe, but I wont use there because oil pump needs 20mm (plus d2 = 16mm, overall 36mm). The left-overs are 22mm plus d2 = 38mm, too long. Only 2mm, but that's only thread length, there is the bull nose of about 8mm on top. Maybe there is not enough space on the other case half. However I will use them elsewhere or store them.

Hi Roland,

Do you have the reference of the kit you bought? ARP website doesn’t specify years for 504-9501 kit and it seems that it’s for a “modern” 930, called them and they don’t know themselves what if fits

Hello

No, only 504-9501 nothing more on the box and invoice. What I have found is this with parts list, but don't know its's 100% same that I received:
