I am missing bolts to fasten the water pump to the block for a 68 400 from a 68 442

Can someone help me with the sizes and quantity and type

Thanks Bruce

The self-tapping screws are 1/4-20. Note the two special bolts with studs on the heads (one 5/16 and one 3/8) for non-A/C cars. With A/C there was an additional 5/16 bolt with a stud on the passenger side.

Inline tube & others like Fusicks sell a whole correct bolt kit for the water pump & timing cover. Inlines part # is 10825 & it's $26. It comes with everything that's in the pic that Joe put up

Bruce, let me know which ones you need and I can send them on with the alt brackets for a few bucks more. Standing by.....Let me know....We have had conversations about parts in the past but never have followed through with anything yet... Am I the only one?

Yeah, Yeah. I have been drinking again and my GAF has been bent for a while.
Tired is as tired does, lol.

Thanks for this post Joe... this saved my butt.. the factory 1979 Oldsmobile Service Manual does not have this Figure. It has very misleading and lack of info on this.. In the '79 manual engine torque list it says 13lbs. in the cooling section is says 22lbs, OK '69 spec was 25lbs. Yes but what bolts????? no figure in it..

Sadly, that is very indicative of the decline in the quality of GM service manuals over the years.
