Default Hardware for Windshield Wiper Arm Control Valve

Hi,

I have a 1970 and I'm trying to install a windshield wiper arm control valve. I have the bracket but I don't have any of the hardware that connects the valve to the bracket and the bracket to the car. Does anyone have this information? See diagram below.

Thank you!!

Do you have the nut plate with the studs still there?

Did you look at Zip where the illustration comes from? Corvette Central has the valve and bracket too. With those two items you just need the appropriate fasteners. The bolts and J-nuts are GM part numbers 9409107 & 3826920. Do a search on the vendor sites for those numbers and choose the combination that gives you what you need.

Thank you! I do have the studs (one is half broken but I think has enough thread left), and have one of the nuts that screws on to it (it's a nut with tooth washer) but I don't know its size (it's 1/4 inch I think). Do you know the part number of these nuts? Thanks again
