To: DJ and Flamingo;
Your posts caused me to look into the matter of cap bolts vs. studs to fasten the water pump.
Found in JS, Revised 1997, Section Early 1928's, page A-7:
"Area 7, Cooling System - some water pumps were attached by dome-headed bolts (cap screws) like the timing cover bolts"
The good news is that cap bolts make it much easier to remove and install a water pump without moving the radiator (although it helps to remove the shroud). I just did this procedure with a little bit of maneuvering.
The bad news, for my particular car, is that the cylinder head is a Ford script "service replacement" head so not the original early 28. Although it had the cap bolts for the water pump when I acquired this car ten years ago, they are certainly not original to the head.
For the moment, I will be satisfied to find early head nuts (3/8 vs 7/16 tall) to be correct for the year and for the shorter studs. Looking for the head nuts now. I'll leave the cylinder head for another time because finding a genuine early 28 head will be problematic.
Thanks for your interest in my car.
