Okay, last installment for tonight!
I went out this afternoon and cut out the replacement drain channel parts. I am doing this in two pieces rather then one just to ease getting everything welded in.
These are the tall covers that keep water coming off the upper cowl from splashing down on the fresh air vents. LH and RH.

These are the flat patterns for the actual channel that goes under the cover. One is left, one is right. I'll get these bent up tomorrow.

I modeled these up last Monday... It was 9 degrees here, I was NOT going out to the shop...
Here are dimensioned drawings if you want to copy them. Anyone with a tri-Five with rusty cowls will need these.
The covers, 1 right, 1 left, mind the bend, this is the right hand side.

This is the flat pattern for the channels. Again there are two needed, 1 left and 1 right. This is the right side.

This is the right side bent up.

These are some screen shots of my computer models.
