i lost my washers and nuts for my head studs. does any one have a part number or know which nuts/washers will fit on my gsr head studs? i need to know asap thanks for any input.

 

Call ARP, they sell them seperately. Dont use other crap with ARP products. I know because I once bought a brand new set from Egay. And two of the nuts werent the right size. Pissed me off but called ARP and got the right **** in the mail.

 

do you know the part number by chance?

 

Sorry bro, its been awhile. I checked my receipts but I couldnt find it. Just give them a call. Theyre simple with it. Make them work for their money.LOL

 

Good to hear! I seemed to miss place a washer.. Would it be okay to use any similar washer??

 

That defeats the purpose of ARP products

 

If you call them, they have the individual item part numbers.
