69 Coupe. I’m doing some final tuning on my recently reinstalled engine. Had a makeshift tuning tool but need to get a proper one so I don’t screw up my diaphragms. The West Coast Usual shows only one with a part # 386-310. The picture doesn’t depict the necessary slots to hold the piston steady and the rep wasn’t able to verify that it does, in fact have them??
** I should have mentioned. I have the Strombergs off a 73 XJ6 on my 69 FHC
Are there more than one kind, and/or is this one what I need?
Thanks
Mark
