These are made here in the USA in our shop.

If you’re going to do a ground up restoration, you might as well build a rag top Bug.

This is a 1956 oval window Bug. Here we’ve installed a Grumpy’s Metal 2 fold sunroof opening. It’s dimensionally the same as original, and comes complete with our assembly which fits perfectly in an original opening or ours.
