I am having the whole interior redone on my TR3A. The judging guide says it was fastened with #4 slotted screws with cups. Is that just the door panels? The screws in the panels in the sides seem larger. Were they flat or domed sheet metal screws. Do the big three sell a screw kit for the interior? I appreciate the help in advance. Photos and descriptions would be terrific.
All the best,

Welcome to the forum
Depending on the commission number of your car, that is, the point when it was manufactured, you may have some reinforcement members made of hardwood. If you have the interior apart its easy enough to see under the scuttle, behind the door panels, etc. Depending on the material, wood or metal, you will be using either a wood screw or a sheetmetal screw.
A review of my notes and both the Triumph Spare Parts Catalog and Standard-Triumph Hardware Catalog indicates the following:
For attachment of
SCUTTLE EDGE ROLL TRIM
DOOR PANELS
TONNEAU CAPPINGS
DOG LEG PANELS
For wood, use part number SP.89H2/CP - No.4 x 5/8" Oval Countersunk Head Chrome Plated WOOD SCREW
For metal, use part number YA.0165/CP - No.4 x 5/8" Oval Countersunk Head Chrome Plated SHEET METAL SCREW
Both of these screws look identical after attachment. The wood screw has a short lenth of smooth shank below the head and before the threads begin. (like all wood screws)
With both of these No. 4 screws use No. 4 cup washer - SP.132B/CP
All of this hardware should be chrome plated.
Note 1. - screws are slotted head type.
GOOD LUCK
