Very nice Mr Drillin - rectangular headlights... I thought the Mk1 had 4 round lights, like the Mk3? Maybe I'm wrong... I know the Mk2 had square lights (like yours), I had a Mk2 ex BTCC for a while, although that had been modified to take round lights.
Recently, I've made a few bits for the car....:

Blue arrow: A compression strut. 5/8" UNF threaded holes at either end, the nearside end is LH thread, so turning the bar clockwise or anti-clockwise lengthens or shortens it by screwing both ends in or out... The pale blue arrow points at the LH threaded end piece, which I also had to make.
The green arrow points at an extension to the steering rack arms (track rods). They've already been extended once by being cut & welded; I figured a bit of extra length with adjustment was needed this time. Besides, the rose joint is threaded M10, whereas the track rod is 9/16" UNF... so the extension bar is threaded with both. Both RH threads this time, so to extend the arm one turns the track rod, unscrewing it from the extension & hence lengthening it.
Finally, the yellow arrow points at the new steering pivot, replacing the old ball joint, which would catch on the brake disk if fitted. A closer view:

Top & bottom are threaded M10. The rose joint through shaft is 10mm; it buts up to a shoulder that you can't see in the picture; the pin is 13mm above the shoulder, tapering to 11.5mm to go through the steering arm, before going back to M10. Not terribly difficult to make, the taper was the only critical bit, so it seats firmly in the steering arm.
Finally:

The sump you've seen before, somewhere.... the blocks that hold the steering rack in place are my doing. Nice & chunky to take the forces...
