WCSTA -09- Coupe into Speedster conversion

While this project has been on going for 2 years we wanted to take our shot at this very generous prize in hopes of taking a little expense off of what remains left to purchase on what has turned out to be a very extensive conversion. This project car belongs to a local friend of mine who sort of late in life caught the 356 "bug" from hanging out with me over the last few years. He of course found himself wanting a Speedster but with these cars now well into the quarter million dollar+ range he wanted to explore other options. He finally settled on building a coupster as it would be something he could jump in and drive anywhere without the stress of such a large investment at risk on public roads as he wants to actually use this car...a lot. Besides his wife was would never allow him to spend that kind of money on a car. As we talked about the project I made clear to him that if we were to build such a car from a coupe donor then it was all the way or nothing. Anything short of a full and complete detailed conversion would be an enormous waste of both our time, his money and a donor 356 chassis. If its a custom Hot rod then you certainly have latitude on what you're going to do but as he wants it completely stock correct then I told him its all or nothing if you ever hope to cash out ahead of the game if and when you decide. So by the end of this build the intent is to have a car that is a correct original Speedster in every respect and detail save for its coupe chassis #. By the end of the build Dr.John should be just fine with his investment as original speedsters continue to climb in value this car will most certainly ride their coattails and will be capable of commanding a strong percentage of what a real speedster is currently going for as its still a real Porsche 356 and again will be a speedster in every detail except for its chassis number. Once our game plan was set I contacted Rusty Tubs for our donor car. After picking out the one we wanted they were good enough to arrange for media blasting so I could hit the ground running when it arrived and then finally crating it up for shipment out West to us. Our clapped-out '59 donor coupe was in the mail to us a few weeks later.

Here are a few shots of it the day it arrived. More shots of it can be found here: http://www.abcgt.com/forum/14-356-Resto ... oject.html
Thanks for looking and your consideration!

thanks!

Thank you Per!

After getting it uncrated and into my shop the first thing was getting the chassis prepped and stabilized with a sub-frame/holding jig. Not much integrity to speak of with the frame so rotted and the roof removed. Below are a few shots of that phase. If you care to see and read more about it you can look here: http://www.abcgt.com/forum/14-356-Resto ... 6&start=12 As of this entry the frame repair has been completed and am into the actual conversion phase of this project. Thanks again! Justin

The longitudinals on this chassis were severely rotted so I was in no real hurry to open my first one up. I decided to work my way back to them by first addressing the forward compartment from the toe-board bulk-headwall to the front torsion tubes. Below are a few shots of that process. More details and photos of this phase begin here: http://www.abcgt.com/forum/14-356-Resto ... 6&start=60
Thanks for looking! Justin

Sharing the completion of this story; at least as far as I am concerned. My involvement was to complete the repairs on a severally rusty Coupe donor chassis and assemble a new Speedster body on it. My part was completed a few years back and this car is now in Wisconsin at a specialty restoration shop for final body work and paint.

just a flash coat of epoxy but it will most definitely need a skim coat to be perfect before its in final paint.

The following day I staged the car with every original speedster part that I own to give a more complete picture as to what the finished car will look like. Rule number one for this project was that it had to be a fully completed conversion in every detail possible and its ability to accept a real Speedster windshield and top frame assembly an absolute must. The final body and underpinning details had to pass the smell test and its original coupe chassis number becoming its only real giveaway at the end. Anything short of that was a waste of all of our time and effort I stressed to my buddy. Anyway, another derelict 356 saved though it will be spending its second life in Speedster form.
I'll post my mock up shots of it next.

Thanks for looking!

Thanks Gordon, it was a real learning experience for sure.

Thank you Antoine.

Chassis began life as a '59 T2 coupe so all chassis details were changed to T1. Original tunnel was rust repaired and convert to T1 configuration.
Corners of the dash and A pillar left raw and rough. These areas would be coated in lead originally and will before its all over.

Thanks Bill, I've seen that episode a couple of times; a great build.

Chassis was set then confirmed squared at the torsion tubes and a tubular holding jig installed to supply integrity through the entire build.

The back of this chassis was more deeply rotted and compromised than initially thought. It had to come off of the rotisserie to allow just about everything from behind the rear torsion housing to be removed.

Windshield frame and dash mounted and set by this point. Initial top frame mock ups to plan a few steps beyond. The new supplied pieces are very basic and raw so you can imagine all the prep and planning it took to get all of this to fit together properly.

Lock posts and lateral closing walls installed. You can see some of the heat and manipulating it took to get those walls in. Ready to begin building on top of them now. Rear cowl being fitted first and will build outward from this panel.

Part 2 coming up shortly.
