I'll describe work done on the suspension and cooling system in another post, but here's info on the most recent work - repairing the dashboard and starting rewiring.
Dashboard - painted over vinyl, wiring problems and a crude patch over the radio aperture.
I obtained a spare dashboard in better condition - looks like from a MkIIa Sprite (1098cc and disc brakes) with underdash cushioning strip (removed in pic below, also original vinyl covering removed).
Like many early Sprite dashboards this has extra holes for switches and gauges. The two extra gauge holes were blocked with a piece of aluminium pop-rivetted on the rear of the dash (and hoping that the fabric covering wouldn't sink too much...). Rust was removed with wire wool and a covered with a quick spary with matt black paint; the aluminium pastch was sprayed too.
I had some vinyl from an old black-out blind - got from a skip in the 1990s. Raided the old spares box for the correct heater switch - came from a 1977 850cc Mini van I had in the 1980s (all that's left).
New Lucas switches purchased from Auto Electrical Supplies and Mini Sapres Centre. Let's see how good the non-UK manufactured Lucas components are (bearing in mind the originals were not always perfect, particularly with age). New wiring harness and choke cable from Austin Healey Spares.
