Tried mocking up a cabriolet rear seat using some seat bolsters from a friend and insulation foam.

As an experiment to see whether it is feasible it seems to work.

The height of the rear seat on my CMC seems to be higher than in a cabriolet, resulting in the seat back protruding above the sides of the cabin. Also, because the seat does not have a slope on it, the seat bases don't sit exactly right.

In terms of width, there appears to be plenty of room to accomplish a reasonable facsimile of the cabriolet rear seat, including the central hump and the sloping sides that are used to support the seat backs when they are folded down to form a parcel shelf.

In order to properly complete this it probably would need the entire rear seat of the body removed and recreated.

This is a lot more than I was really prepared to undertake, especially as really I am eager to finish the project "as is" and not make more work for myself.

The other problem, that I can see, is obtaining original 356 seats from either ebay or somewhere like Pelican Parts. Either way you are looking at serious investment. Also, the carpet will now need to be custom made at additional expense.

It was something I wanted to do and am glad I tried out, but in the end I think I will be going with the rear seat that can be seen in Joe Soltis' CMC. (TIA for the plans Joe)

If anyone does ever try this I think the results would certainly be worth the effort and cost.

Nice job with your rear seat mock up. Two things that I noticed from your rear seat picture. I think that the bottom of your seat is higher than a 356 Cabrio. If you have opportunity to measure a 356 seat I think that you will find that the seat bottom should be closer to the floor. I think that the change in rear seat height occurred with the introduction of the 356B. It may be necessary to cut the bottom of the glass and install a mold for the bottom rear seat cushion.

With the 1964 and 1965 356-C Cabrio the rear seat back is shorter to avoid the problem of the seat back sitting to high above the passenger compartment as is visible in your picture. If you go the e-bay route get the 64-65 Cabrio rear seat!

You can find some excellent information and pictures in Laurence Meredith
Joe,

The Chesil rear seats your photo shows are the '2+2' option.

The outer bodywork is unchanged from the standard car but the battery box is relocated (normally behind the seats) and seats contoured back into that area and down either side of the centre tunnel creating two distinct seats rather than a bench.

It involves a new GRP inner mould for the inner rear section of the passenger compartment (and can be cut into existing cars for a conversion, I believe)

Heres a picture of a car body undergoing conversion at chesil from a visit last year - scary!
