Gotta love these frame off rebuilds with everything still attached to the frame.
Why take all the time and trouble to separate the chassis, and not strip the chassis bare?
How can you paint the chassis with all that crap still bolted on?
It is not until you take the engine out that you get in to the Y and see it there is any metal worm in there.
Plus you turn the chassis over to paint all the bits that rust, like the underside of the front box where the closure plate and the pedal box attaches.
