Interslice on eBay is a great place to get a lightseal kit. I have gotten 2 form him. Look him up it is quality stuff and he includes a nice instruction book and he has more information at his website. I looked last night at his stuff, he didn't have any generic kits, so you might have to email him to see if he is going to list more generic kits. http://www.kyphoto.com/classics/sealreplacement.html and http://shop.ebay.com/merchant/inters...Q_fromZQQ_ipgZ
