When ordering a new valve from gm does it come with the mounting bracket?
It looks like you can't remove the bracket on the ones I've seen.

 

yes it does

 

Yes it does come with the bracket, i just ordered one last week.

 

just got mine yesterday from gmpartsdirect.....comes with one

 

thanks.

 

ALmost ready to do a c4 upgrade from ED. He has mentioned on several posts to use the 1LE proportioning /combo valve. I have read the thread pitch changed mid year '89 which is what I have ?
So there would be two valves, one early '89 and down and one late '89 and up. I don't trust GM as far as production dates and what was installed that way, how would you know which one you had by looking ? Also any part numbers would be appreciated.

Thanks,

Bill E.

 

I just got screwed by GM's mid year change on my 89 IROC, anyone need a late 89-92 prop valve? I am doing a C4-HD upgrade and I purchased the 1LE valve for late 89-92 and it's the wrong valve. The 82 - early 89 cars have a much finer pitch thread on the tube nuts then the late 89-92 cars. You can use a thread pitch gauge that come in most tap and die sets or you can buy them for a few bucks. The 82 - early 89 cars had a finer thread pitch of 1.0 and the late 89 - 92 cars had a more coarse thread pitch of 1.5.

Here are the part numbers:
14089496 1989 1st design: M1.0 tube nut threads (For 1982 - early 1989 applications)
10164112 1989 2nd design: M1.5 tube nut threads (Late 1989 - 1992)

 

89 Iroc Z: Check you pm's, I am interested in the valve.
