We are breathing new life into an 11 window bus, starting by adding 8 sky windows and a sunroof. 2 more side windows and we’re building a 21 window deluxe. That’s inspiring!

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.

BBT is now selling our 2 fold and 3 fold conversion kits for your 1949-1955 Bettle and 1956-1966 Euro Bug.

Why drive a 13 window when you can have a 21 window bus?
In 1 week, we transformed this sweet looking ride into an epic 21 window beach wagon.
And look at the fit and finish of our trim!
