i am in process of my rebuild. When i removed the water pump/timing cover i broke a couple of bolts. where can i get a set(besides the dealer)? i broke the long ones that go to the water jacket on the front of the block.
See http://totallystainless.net/totally.html for the bolts. Last time I checked, they didn't have the studs. Nice folks, very into cars of all types. They have all kinds of stainless fasteners for almost every car. The prices are very reasonable, less the $8 for the water pump kit without the studs.
The studs are a Motormite item available at your local Advance Discount auto Parts store.

I have a problem, my motor got torn down last year, and I guess I wasn't as organzied as I thought, and I can't find me old water pump bolts. No biggie, I bought an ARP Bolt kit and the bolts that come in the kit for the water pump don't fit..... well, two do, the others are all a tad too long. I decided to buy the water pump stud kit, but I don't remember where they went.... anyone happen to have a diagram to show where the different bolts lengths go in the water pump? PLEASE? haha. Thanks
I'm in the process of making a diagram where all the WP bolts go but at this time I haven't finished it, so for right now this is the best I can do for you .

The last one I typed I don't have, yet. It should be 2-3/4 to 3 inches long. I bought a 2½ and not much of the threads go far enough into the timing cover. It's for the bolt hole that is between the two water ports on the upper left of the water pump. I'll have that info later tomorrow.
The bolts for the water pump pulley to be used without a belt-driven fan are 5/16 x 3/4 24-thread. The two rearmost cover bolts which bolt the cover to the block (not shown) are 5/16 x 3/4 inch. I am scavenging those from an ARP bolt kit that I have which can't be used with late model timing covers. Only a few from the kit could be used as the kit was designed for older model 289/302/351W timing covers.
