Thank you all. I believe the seals sold from LMC come mainly from Precision. From what I gather on the lockstrip I've heard they are somewhat different from manufacturer to manufacture. So, for example if you use the Steele gasket then you want to use the Steele branded lockstrip. Regarding, the slider I've read somewhere that one from a 1992-1996 Ford F150 or the aftermarket version for those years of Ford will fit in these trucks as well?
