Technical L6 waterpump bolts.

Hi all. Is there a bolt kit I can buy for a Chevy 250 L6 waterpump? I believe they're 3/8" unc.
Thanks.
Roger.

 

Ironmongers don't have 3/8-16 bolts?

If you have a pump, you can put a longer bolt through and mark how long it needs to be to extend 1/2" (13mm) past the mating surface. Then measure the length from under the head to your mark, that's the bolt length.

If the available lengths are not quite right, you can get longer and cut off a bit.

That's what I'd do, and I live where one can buy "kits" for just about anything.

Took mine to the hardware store and bought bolts that stuck out around a 1/2 inch past the pump.
Ya need to know if an alt bracket is used by one of em.

 

Thanks for the replies and advice chaps, its much appreciated.
Roger.
