In 2013, we went though the entire brake system and repaired the parking brake as well. The 305 was yanked out after it started knocking and was replaced with a 327 we bought cheap and disassembled. Had it bored 30 over, a mild cam installed and reassembled. We stuck with the 3 speed that was already in it.
The previous seat must have been out of a car, the legs were too short and had clearance for the driveshaft tunnel. My dad claimed he always hated that seat and was glad to swap it out for an original reupholstered seat we found for a good price. The drivers side door was swapped out to a much better one I found at a flea market.
Currently, we have a set of 6 lug Rallye (Rally?) K5 wheels that will eventually be painted and put on. The steering gearbox is sloppy and will be swapped out for a better one I was given. The passenger side axle seal leaks too so that need to be addressed.
We've taken it to several shows, either being local or a few hours drive, and is happy to motor along at 55-60 mph. Most likely the entire rear end or just the ring & pinion will be changed out.
We'd like to start restoring it one day, but yet its fun just to hop in it and fire it up and cruise on down the road.
