At least I'll feel comfortable in selling them once they've been rebuilt.
UPDATE ON OTHER PARTS:
As for the other parts that are left, well, there's the air filters and adaptors, gearbox and turbos that are left. I'm thinking I may as well just keep the filters for the Silvia, and the exhaust which I thought would never go went on Saturday. Unfortunately out of the money I've made on selling the parts, I have had to purchase the bunky for $1500 and have paid close to an additional $1500 for parts and labour to get her running well again!
Oh well. I've managed to pick up a couple of private jobs lately which should help the cause.
