That's a 1970 combination valve. It can be made to work on your car, but the setup that originally came on your '68 looks like this:

That one can be made to work but is not like the factory 68 distribution block and proportioning valve combination in bracketry.

There is a reproduction 1968-69 complete distribution block / proportioning valve with lines now available. Even has the switch. Under $156. Very nice copy of an original.
