Does anybody know a good place to find the 14089496 Proportioning Valve. Trying to find one for a LS1 rear conversion in my 87 Z. Not having much luck going thru the usual sources. Is there a replacement Part# the replaces this unit.

Thanks

 

Managed to dig up some further information that might help the next guy. The 14089496 proportioning valve (JE1) cross references over to AC Delco 172-2004. BUT I actually need the 86-88 J65 valve and that is 14089497 which references over to AC Delco 172-2005. Luckily found one on Amazon for a little over 80 bucks.
