Do you offer the parts/o-rings for the other versions of the combination valve? This is the one from my 72 Firebird.

I'm still working on the kit for the metering valve and that's what's holding up a rebuild article. If you can't wait assembly is just the reverse of disassembly. These are the seal kits:

I hope to have a kit for the metering valve "soon".
