one piece window conversion

[skip99]

can someone post a picture of a 47-50 1 pc. window door ,interior side?
I need to see where the parts on the regulator mount in the door. I should be able to tell by the visible screws...thanks

Im converting to 1 pc, I have the regulators..

i considered using the single arm from my 51, and just adding a pivoting arm to carry the longer window, but i notice on the 47 type that there is another channel that welds to the center of the door just below the armrest.
and I would have to cut the tension spring off the 51 style so the window would not hit it, ( is the spring just to help when rolling the window up?

I also plan on using just the bottom of the 47 type window frame, so the glass will fit my 51 channels..
