I am in the process of restoring a hard top for our 1957 BN4 (longbridge) car. It was not original to the car and am wondering how others have mounted the top on the longbridge cars. I am using a BT7 as the mock up car and it has factory locating tubes welded in the car for the front pegs of the hard top. The longbridge car does not have these tubes at the "B" pillar. How should I mount the top? I guess the pins will just hang down in the space where the top sliders are but nothing will positively locate them. Should I weld up some make shift mounting tubes that will bolt in place with the top sliders? Any thoughts or pictures would be appreciated. Jim.
