Hi all I have another purist question. What are the size of the screws that hold on that heater hose attaching piece that fits to the bulkhead on a tr3. I think they are short and stout sheet metals screws about 3/8 of an inch. Does that sound about right?

Not totally positive (and don't have time to look it up just now), but I think those are YJ 2565 (same as the steering column blanking plate), which are a special thread for clip nuts and have an 'oval countersunk' head.
 
Sp I'm going to use 10 X 3/4" long self tapping hex head sheet metal screws. I have a few of the original type but gave up trying to match them up in my two horse town.

Good Luck, Tinkerman
 
Thanks Randall for looking. I think the screw is the oval counter sunk (0). The ones I have that I think are right are very short, but if I remember right, I want them that way so they do not interfere with the hose hook up on the other side. Hey Randall, is the picture you posted from the parts manual shown on the tr3 home page?

Not sure which one that is. The image I posted came from the "Hardware Catalogue for use with Standard Triumph Vehicles". ISTR this was originally scanned by Mark Gendron, but I can't find his web site at the moment. However it's posted in various places, like
