My 289 car has a top with no door pull's and side curtain's. The biggest issue I came across was door alignment, once properly aligned no problem. Now the 427 car came with no door pull's and a remote opener, no latch. So closing the door became a issue, didn't like the leather strap idea. The 356 Porsche Speedster's came with polished alum. door pull's that after used, would lie flat against the door card. But @ $159ea. too much money. Sooooooo..... what other cars use those, and lo-and be-hold the lowly little Fiat 500-600 use the same type pull (Also polished Alum) for sum of $39ea (Sorry, sorry, these show pounds, but you can find them here, in dollars). They work great, look good, and may be the answer for your issue. My $ .03 Cheers TommyRot.
