I ordered a new lower wishbone from David Geralds, which duely arrived. I then got all the front suspension arms, and a few other bits and bobs, off to the powder coaters.
I had decided to paint the uprights rather than powder coat them, so, while the wishbones were away being coated, I gave the uprights a final cleanup ready for painting. The thread on one of the uprights was rather rough and had become badly pitted by rust. The rough thread had eaten into the brass trunion threads and, as a result, the trunion had also become badly worn. Both the trunion and the upright were replaced. The thread on the second upright was fine, but the second trunion was also replaced as a precaution. The uprights and trunions are early Spitfire/ Herald items and available from Rimmer Bros. I ordered a trunion rebush kit at the same time.
Having given the uprights a final soaking in Deox-C and a clean, I gave them both two coats of POR15.
The streering arms were both badly rusted, but came up fine after a couple of days in Deox-C. Unfortunately all 4 bolts had been broken off and seized tight in the threaded holes. Whilst the Spitfire/Herald steering arms are easily avaiable and only a few quid each, they are the wrong size! The arms are apparently Standard 10/8 items, but don't seem to be available anywhere. So I had to send the originals away to get them renovated. I discovered later that Mike Brotherwood (http://www.mikebrotherwood.com/Parts.html) does some hand made ones that look like they may fit.
So, following a trial re assembly of the uprights, this is as far as the re assembly of the car got in 2010:
