Rocker Cover Screws, Which screws on the underside? Options

[Arno914]

Hello,

on my 1971/-4 I recently cleaned and resprayed the rocker covers.
On the top I have the correct hardware to attach them, plastic rivets and screws with spacers on each end under the fender lips.

In the bottom part, there are three large holes in the covers, apparently for M6 (?) size bolts (3 each side).
On my car however, there where 3 holes randomly drilled to attach the covers with small sheet metal screws. Seems to be "original". The fit is correct.

Question: Did the factory attach the underside of the covers this way? On the early cars maybe? Are there nuts in the longs for larger screws on "later" cars? (Mine doesn´t have them.

I added rubber spacers to help drain water and dirt upon reassembly.

Greetings, Arno

My best guess (as it happened to mine), the original rocker hole got rusted and screw wouldn't hold. PO drilled new hole into sounder metal.
Those Phillips head screws were awful to remove. I filled in all the holes with metal epoxy, sanded/painted, and redrilled to an M6 Hex screw (yellow zinc) and washer. MUCH easier to remove & reinsert.
