Need some info on 64 Dodge Polara Top install I wouldn't be too concerned with side tension cables on this model. I like to make the pads (not universal) to fit close to the top edge of the side rail. Keep the pads thinner so this will allow the top to fit tight to the side rail. After installing the rear curtain , start installing the top by gluing the 1/4 flap to the 1/4 rail. I find this holds the roof in a spot where it needs to be. Then it allows you to pull the top rearward toward the rear bow (always keeping an eye on your center and side seam mark on rear bow) and belt line.
