In the pics you will see a broken vacuum part. Does anyone know what the part number is and if so, where can i find a new one. It is on the large hard line going to the master cylinder and t's off to the valve on top of the valve cover.



The story behind it is that i was having issues with my car shifting early. 15/25/35-ish. Trying to adjust the bowden cable was doing nothing noticable. Then one morning it wasnt shifting out of 1st until around 25-30 with very hig rpms, of course and a real hard shift at that. I did not even get out of the neighborhood. At home i found this piece broken. I did a quick super glue and some "Goop" job on it. Today my transmission was right where i think i should be. shifting at just the right rpms (it feels), with no flare or hardness.
So maybe anyone else having issues might look for something like this also.

Dave, that link shows something different. That booster vacuum hose has only one "t" on it. Mine has that valve(??) in it with two connections on it. Is that broken piece (valve???) in the middle of the booster vacuum hose replaceable without replacing the entire hose?

Nope, you'll have to replace the whole unit. The one pictured may not be like yours because they used more than one type for the 1980 model year. Check the last six numbers of your VIN to see which one fits.

You could visit you local junk yard to find a replacement. Although it will be brittle as well, but it won't cost nearly as much.
