I’ve replaced several 94-98 tops with Robbins tops. Been happy with the quality. Wish they lasted longer, but sitting in the sun in FL anything over 5 years is bonus time for a top.I ordered mine from NPD, it's the 36 oz Haartz Pin-point vinyl in white.
For my 68, I bought the Haartz Pin-Point white vinyl as well. Haven’t put it on yet, so jury is still out.
