I have a 1972 22 foot Barth. I have replaced all the brake lines. The flex lines can look fine, but the collapse internally. I had to special order new flex brake lines. Save your rotors at all costs. Those I cannot find. I ended up changing out the original 454 with a new crate 454. That has worked out well. Engine went in through the door.

Go Parts shows them for $52 each. Our 81 Euro got new ones from Napa without any delay. Wonder why ours that is also a 22' has a 350 truck 4 bolt main engine? These have to be almost identical except for the engine.

I have a 22 foot, 1972 Barth. Replaced engine and transmission 3 years ago. It is operating well. Front brakes were a project, but they are working. If anyone has parts as mentioned above, I would be interested. Trim, lights etc. I am going to replace the ceiling, had some leaks. Do not have a plan for that yet.. I will probably put an aluminum roof on it for a race view platform. The wood grain siding film on one side has deteriorated. I was advised new material can be applied.
