Hi All,
I was searching for heater diagrams yesterday and found some here, (Thank you "squeeze" for the info), so thought I'd join and contribute.
I have a '59 3200, BBW, long bed step-side, original V8 edition. It now has a SB400, 4sp, partially done interior, and natural copper patina over the original turquoise blue.
I'll get some pics soon.
Now starting the install of a rebuilt deluxe heater I've had laying around. I'll take pics of the parts and document the task.
Dave
