At least you're keeping us current
That's not sarcasm either, I'm genuinely interested in seeing how this project is doing. Temps around here are below or at freezing and I have to work on the donor car's body outside while the Miata chassis is inside the garage. There's a tiny space heater in there but you still need gloves and a coat and everything.
I wish Hoopie would give us an update. He's working on a Karmann Ghia which uses the same exact VW chassis that my Type 3 does. However the Miata is much narrower than the Prius.
Today I need to get the VW ready for the swap. The idea is that I'll lift the VW body off it's chassis with an engine hoist, roll the old chassis out of the way, roll the new Miata chassis from out of the garage and under the body, drop down the body, then roll the whole thing back into the garage (which is uphill so that will be a problem).
