Here's how I made my windows tracks. It's very simple to make.
Here's the glass (yellow tape on the glass was used for shipping reasons, may leave it on until the build is done)


Using this for the inserts (picked it up at Pepboys for $20)


Measure your door

1x1x16ga tubing

Cut off one end leaving it 1x3/4

Cut in half down the middle on the back side

Apply the molding

Bend each track individually to the appropriate contour

Fit it to the glass then tack weld it
