Since I got this project I've been sweating doing this repair. I worked it up to be some big complicated job. Turned out it was cake like many have said. I used machine screws and rivnuts to make it removable so I can drop out the rear window when needed.                       
Nicely done! You've obviously noted there is only one drain point and the trough angles downward slightly toward that drain for obvious reasons. However, slightly tongue I cheek, I'd suggest drains at both ends. I had my 36 parked on a fair incline, side to side, and unbeknown to me the drain side was uppermost. Following some heavy overnight rain when I jumped in and drove off, turning to head down the hill, there was a minor tidal wave of rainwater toward the drain which was overwhelmed with the excess water spilling over the trough and soaking everything in its path. Not a catastrophe as I had no interior, but I would have been pissed if I did have. Don't park on a hill in the rain! Chris
really nice work very impressive doing the same job to day on my 32 using upac parts impressed with how well they fit
I agree. Originally I planned on draining from both sides. When I take it down to prime & seal it I'll add the additional drain
I had sheet metal damage at the floor board/ running board area, where the drain hose from the rear window gutter attached over a small ****** fixed to the floor was loose, allowing the water to leak outside the ****** and onto the floor. When I made the repair, I made a larger size ******, allowing the drain hose to go inside the ******, to prevent recurrence of the leak.
