The sand blasting and powder coating of a top frame, followed by the installation of
real wood top bows is the hallmark of a superior restoration.
Paint your bows with exterior oil based paint and the top bows will last
as long as the outside trim on a house.
The wood front bows on early Ghias are recessed like the original in order to allow the embedding of the complex latch mechanism into the wood bow. We had taken an original wood top bow (from a Karmann Ghia many years ago and preserved)and duplicated this wood bow recess. If you have a plastic rear window Karmann Ghia convertible (early 1969 and prior Ghias) then our wood top front bow should receive your mechanism nicely.)
In the later Karmann Ghia convertibles there is a pair of wood bow hold down plates, one in each front corner. Reproduction wood front bow holder plates are now available. They seem to have large tolerances (angle of shaft varies, etc.) but will work well if you align the wood bow according to our directions. If the wood front bow does not just "drop into place" then the situation is easily rectifiable without sending the front bow plates back. We do drill an oversized hole at each side of the wood front bow to allow adjustment and aligning of the bow, especially when using imported front bow hold down plates.
The rear base wood bow in early Ghia convertibles is made much more sturdily (infinitely more sturdily) than the plastic wood replacement bow for the rear base of early Ghias. We laminate upholstery grade poplar using high pressure and modern marine adhesive and then shape the wood bow to fit our chassis section that we use to finish fit these wood bows.
