whats rear brake proportioning valve worth, original. bracket alittle rusty and nut on end very good. #234-7

If you are talking about the one by the booster, they are being repopped. I'd say originals are still worth $125-150.

not the one by the booster the one that bolts on the subframe right under the drivers door. thanks

Are you thinking about selling one? Personally, I don't know why someone would want a used one. They come with many kits. It's nice to stick to originality but some things don't matter in that regard. I've never had anyone come up to me and ask, "Does your car have the original Prop Valve?"

Clean it up and buff it to a nice sheen. Post it on eBay and let the bidding begin. Then you will know what it was worth if it sells.

I'm not sure if the one on the subframe is being repopped, or not. I think originals were selling for slightly under the one by the booster (technically, the one by the booster is a delay valve) I'd say $100-125.

They sell on Ebay for between $75-$125. I guess it depends on date codes, whos shopping for one at that time, and the condition.
