TR2/3/3A Late TR3A fuse box mounting

[TR3driver]

Can someone describe for me how the late (post-60,000) fuse box (with the Lucar terminals) is mounted?

I'm looking at an amendment to the factory Spare Parts Catalog, which calls for one pan head #10 self-tapping screw 7/8" long (YA0507), and one pan head #6 self-tappin screw 5/8" long (YA0305), plus only one #10 clip nut (FC2805). I'm guessing that means the #6 screw goes directly into the firewall sheet metal, but I'd like a confirmation if possible.

I checked my earlier car, and it definitely has two clip nuts and two #10 screws (which don't seem to be mentioned in the SPC at all; I plan to add them).

PS the TR4 SPC shows one #6 self-tapping screw, only 1/2" long, plus a 10-32 hex machine nut, which makes no sense at all to me.

Randall,
I'll try to remember to look at the 3B on Monday and send you a picture.

Mine has one screw in the center with a clip on the back. Sorry for the bad pic - ( on my knees, backward camera on the iPad with a small LED light. )

Here's mine, not much better. It's the middle one. Tom

Your assumption is correct. Screw with clip, is in center of fuse block. (as per photo above) At bottom of fuse block is a upside down "U" shaped cut out where the other self tapping screw goes directly into the bulkhead. Just went out and looked at mine as I had forgotten about the smaller screw at the bottom. It seems neither picture shows the small self tapping screw, but mine, a '61 had the hole drilled and when the fuse block was removed for painting of bulkhead, it was bagged and tagged with both screws.???

Mine is like Scots.

Interesting! Evidently some had the 2nd screw and some did not.

Thanks to all.

My 3A (TS72099, March 1960) had the 2 holes but when I was putting everything back together I ASSUMED (you know what that means!) that a PO had drilled the extra hole & carved the u-shape in the box. I felt that one mount was enough so I just left it. That was 20+ years ago. I forgot until Randall posed the question so I removed the cover & viola!

Here's the fuse base on the late TR3A I restored.

Thanks, Don, but your photo didn't come through for me. I get a gray box that says "Attached Images", but there is no link under it.
