Some of our vendors ship unopened goods in original packaging instead of previously returned items with occasional damage, missing parts, and missing instructions without disclosure of that fact, for the same price. I'm not saying it happens, but I'm not not saying it either.

Very good to know. Is there a part # to be sure I get the latest version? I also have to decide if the extra bite (less stretch) is worth paying $100 for studs instead of $25 for Mahle bolts, which I can buy new again when i rip the head off sometime from now.

Thanks for the advice.

Or at least a measurement of the old washers and new washers.

ARP #218-4701 Mazda Miata Head Stud Kit, Packed date 8/01/2016 - (Torque 65 Ft/lbs.)

ARP Washer dimensions: Thickness .120", OD .875", ID .445" (punched, not machined)

Stock Washer Dimensions (VVT Head): Thickness .092", OD .837", ID .450" (punched)

So the ARP washers have 13% more load bearing surface.

I did not mean to start a shit storm. I did not previously know of any past problems with that vendor. My first time ordering from them was for pistons and studs.
