Some more progress over the last week or so. Stripped all the suspension out, arms, struts, steering rack, front and rear subframe a, diff handbrake cables etc have all been removed.
Masked up the engine bay and have begun painting the underside. Just using black Epoxy paint, any spots where there was minor surface rust wire wheeled back to clean metal. Will go over any seams with seam sealer and then do another coat of black epoxy. Very time consuming and messy process but will be worthwhile. Have done the first coat on the front wheel arches and underside of engine bay so far, lots more painting to do.
also made up a new Clevis pin to adapt the e30 brake booster bracket thing that the pedal pull rod actuates to the e90 booster.
