How to Assemble the Front of a Small Block
I just looked at some of my galley plug kits.
I also bought a few "complete block hardware" kits from Year One. MP part # P5249261AB.
It's a complete "block hardware kit" with all of the freeze plugs, galley plugs, distributor bushing, oil filter plate, gasket and "screw", and dowel pins. I'm sure it costs more than the "more basic" kit in the link from Mancini above, but I would try to see if Mancini would have a better price on it if I were doing a complete rebuild. Here's what the instruction sheet lists:

Of course, they don't list any part numbers or plug size in the list for the oil galley plugs, so I took one out of the kit and measured it for you. Here's what the smaller leading edge measures:

Here's what the larger end measures at the edge of the plug (they are slightly tapered):

The instruction sheet says that it is for all 64 - 92 LA engines and 92 - 03 magnum engines. I would go to a dealer and have them look it up. If they don't have a listing for the older LA engines, then have them look it up as an 02 or 02 magnum engine. They may still be available through the dealers....
If you can't find one, PM me and I can split a kit and help you out. I'm sure one of my engines I may do a quick refresh and not need to replace them.
They should be somewhere between 9/16" or 19/32" as a ball park figure. It's best to use the numbers shown in the pictures above to make sure that you get the right ones.
