Redfish makes a good point about the fit, but since you have the gasket out anyway this would be the time to massage it. I would guess today's lockstrip is just as bad as the original, in terms of longevity, and lots of people complain that it doesn't fit as well, either. The corner pieces can be found new, but there is also a shallow V piece in the center of the back that isn't reproduced, so that's another issue. The reason the 67 gaskets are so expensive is that they only seem to make them in small batches. Some years they don't seem to be in stock anywhere. The 68-69 gaskets have much better availability. As Toplscuda says, you need to buy a set of clips and screws for the conversion (repros available), on top of sourcing the stainless trim (not repopped), and drill holes in the right locations. Either way, it costs money and it's a fair amount of work. Done properly, the stainless looks better when new and lasts pretty much forever. If you have the glass out already, that's half the battle -- I would definitely go for it.
