Once again, thanks for all your comments. I got in touch with Jon Goodman, whom I've dealt with before, many years ago, and he'll be sending me an Interslice light seal kit for the back. BTW, I found out he no longer sells through eBay. As he so colorfully puts it, "piracy and fraud and eBay's preference to hide under the bed rather than grow a set of gonads finally ran me off." So you have to contact him directly at JGood21967@aol.com. Hope this does the trick.
