Update report

The following sequence of photographs show the trial fitting of the engine and 5 speed transmission conversion. Jake fabricated and welded sturdy plates either side of the transmission tunnel, with a heavy duty chrome-moly bar to support the weight of the transmission. This week we will begin the process of fabricating a set of custom headers and custom exhaust for the car.

Update report
All of the sheet metal repairs and panel replacement have now been completed.

Lots of progress with the big Mercedes in the Team CJ Coachworks.

Back from being blasted back to bare metal. The news isn't too bad, but a few additional panels will need to be sourced or fabricated.

The following sequence of photographs show some good progress in the CJ Coachworks this week. We also received the interior wood back from Madera Concepts who did a beautiful job refinishing the macassar ebony veneers.

Time to get the sheet metal repairs underway.

I am pleased to report that we now have this exciting project underway. With the engine and drive train removed, lots of corrosion and some very shoddy previous repairs are on display.
