This part helps if you have someone helping you. When you have the covers on..have the other person push down on the spring while you pierce the covers thru the spikes and take a small hammer and tap the spikes down holding the covers in place. Make sure your covers are nice and taut and are on straight. To work the side there are small draw strings that you will draw taut and tie into a small knot on the spring housing,drawing in any slack from the sides. Again, before you wrap up the back make sure everything up to this point to staight, no slack on the front or sides, IF everything is good then have your helper push down again on the springs and finish up the rear, as the front pushing the cover thru the cover and tapping down the frame spikes. You just fished the bottom of your seats! I used NO glue whatsoever on the covers.. Below is the tweed sand, and black vinyl TMI seat covers for a 63 Single.
