I am in the process of rebuilding my 13bt that had bad coolant seals, I need new apex seals, apex seal springs and a gasket set with coolant orings. and I also need corner seal springs and side seal springs (new of course). anyone who might have new or lightly used apex seals PM me with a fairly cheap price, Thanks

 

I may be parting out my s4 13bt soon, but it has 3mm seals. The parts only have 5k miles on them though.
