Water Pump Bolt Sizes?

Hi, I have a '64 401 Nailhead. I'm changing the water pump and one of the small bolt broke off.

I need to know what are the 3 different size bolt use to hold the water pump on so I can replace them all with new one.

Thanks! Kevin

 

Kevin, there are 4 or 3 bolts in 1/4x24-7/8'', one bolt witch is 5/16x18-7/8. Rest are the long 5/16x18 bolts but i can't remember what lenght they have. You have to check it for yourself.

Peace Kacper.

 

Thanks!

Now the question is where do I get them?

I know there are whole kits, but all I need are the water pumps bolts

I've research them online and the 1/4 x 24 x 7/8 bolts I can't find at all.

HELP!

 

You can always get longer bolt and shorten it with saw. I personally buy every bolt here: www.alloyboltz.com .

Peace Kacper.

 

Thanks! You helped me out a lot!

 

Shouldn't that be 1/4 x 20 thread

 

You are right, i checked it again...what i was thinking of when i was typing this...there ins't even that size of thread on alloyboltz...

Thanks.

Peace Kacper.
