Janice, OK, looks close, but not an exact match to the GAF 2388. this bar is metallic and a magnet sticks to it. I may have someone try and tack the tab back on the end.
I couldn't tell if your bar has a tab at the end or is it just flat.

What you are calling a bar is actually a section of "linkage". Linkage is generally the term referring to a mechanical switching mechanism comprised of two or more (usually metal in projectors) rods or bars.

Yes Janice "Linkage". I should have recognized it as such. hopefully a friend my son works with will be able to tack it back together. If he can and it works, I'll still have to operate it through it's motion to see if it's within specs (1/16 gap in reverse).
if it needs adjustment I may not try and bend the tab again. what if I slip a small piece of tubing, or something over the tab? wouldn't that be the same as bending the tab? the idea is to push the spring loaded arm away from the take up spindle. it probably doesn't have to move very much.
if you can think of anything else, just let me know.
I had the linkage with the broken tab repaired. reinstalled in the GAF 2388Z. checked the gap in REWIND, and it was right on 1/16th of an inch. I tried a 8mm reel and it ran through perfectly. I have a 1/4" rubber gas line as the rubber tire. there's just enough pressure on the tire to run the spindle, but no excessive force to load down the drive spindle.
thanks to everyone who posted. I learned a lot about these two projectors.
