A few months ago I purchased a 1963 Pontiac Bonneville combo by Superior coach. After a week of headaches (truck breaking down, trailer too narrow, waiting a week for the wrecker to get off his butt to get them both) she finally made her way home.
As far as the car goes she’s in incredibly good shape for her age. The engine runs quite well, and we’ve already replaced belts, gaskets and such.
The interior is in very good shape. The headliner is in perfect shape, the floorboards are solid, and the dash is still good with all the knobs still functional. The front seat needs to be reupholstered, and the door panels can use some touch ups, but that’s about it. One of the previous owners retained the stretcher and the jumper seat in the back, so those will need to be replaced. Oh yeah, and the minor detail of installing seat belts.
The majority of the work that needs to be done is on the body. It’s got rusted out areas in the lower portions of the fenders, doors, etc. There were some spare rear quarters included with the sale, but they’re almost in as bad a shape as the ones on the car. I’m currently working to find funds for body and paint to have at least that part of the Ecto ready by May of this year.
As far as the conversion will go, we’ve had a few offers from a couple metal workers to help us make the roof rack. Another of our members has lots of old equipment to use as interior instruments. So we’ve got the meat of it planned out, just need to work on the nuts and bolts.
Sure, she’s not a Caddy, but she’s an excellent Ecto candidate in our opinion. ![]()








I got two Code 3 MX7000 lightbars for the car from a local seller, and ordered some blue lenses from Wiseguys. There are a couple rotators that need to be fixed or replaced, but over all they work perfectly.


Here are some shots of the interior showing off that perfect headliner:


Here’s where the attendant seat should be. It was removed and kept by the owner before the guy who sold it to me.





Here’s some close ups of the zippered access to the beacon mount.


Here’s the plug (I guess) for the port as seen from the roof.

Also, we’re very big on fire safety.

And some video for you. Please note that youtube squished the video some. The car is longer than it looks, even though it’s still short for a professional coach.
Engine running and a walk around:
Lightbar test with the blue lenses in place. I have clips on them now, but this was taken before I got them.
All glory to the Hypnobar!
Back in August we made a mockup of the roof rack out of 1/2" PVC, just to get a feel for what the real thing is going to look like and to make sure the measurements I came up with were correct.




That pretty much brings us up to speed. Like I said, I’m working on getting funds to have bodywork and paint done by May. I’m thinking of petitioning a few local businesses to help sponsor in exchange for some advertising - NOT a window full of decals, though. Something discrete and tasteful like a sign we set up next to the car at events or a spot on the scrolling LED sign if we get one.
Let me know if you guys have any questions about the car, or any tips or advice for the build. ![]()
