Need contacts for 308 rear caliper parts

A few weeks ago a friend of mine had rear brake caliper problems on his 308. He brought the calipers to me and I was supprized how much they looked like the 914 porsche rear calipers. The only difference between the two are 10mm spacers between the halves and a slightly smaller pistons in the 914. Since I make the 10mm spacers I put some in the 914 porsche calipers and they bolted right up to his car and he was on his way. The seals for his e-brake lever are leaking bad. Since I have many calipers with this problem and the 308 and 914 calipers use the same seals, does anyone know where I can buy 10 or 20 e-brake seal kits.

 

Thanks John, I don't think we have a Repco in the states. I was told that a company in the Downunder make these kits for the ATE calipers. If you or any of your friends have heard of them I would be greatful for the information, Thanks
