Proper spacebar repair on XT 83-key?

The spacebar died on the last working 83-key XT keyboard I had (I have three, and ALL have non-functioning spacebars), so I decided to finally choose one to take apart and try to clean with compressed air, etc. All of the keys came off okay; I put the plastic parts *only* in the dishwasher (mild soap, warm water, nothing harsh) and cleaned the rest by hand by shooting compressed air into every buckling spring hole. But when it came time to put the spacebar back on, I noticed that both ends of the spacebar have two little "hooks" that are supposed to hook onto two little prongs of metal underneath the top of the assembly. These provide necessary support, as the spacebar will bend if pressed at the edges instead of going straight down. Only problem is, I can't seem to get these re-hooked! The only way I can see getting the spacebar back on, barring some trick I don't know about, is to take the metal back off the assembly and try to re-hook it from underneath. But I'm terrified that, if I try to take the back off, 83 buckling spring assemblies are going to fly every which way from the unit and I'll be left with a worthless hunk of junk. It also doesn't look like it was meant to be taken off anyway, as one of the metal tabs on mine seems intentionally bend downward to prevent this. For those who need pictures, I've taken some snapshots of the problem and put them here: ftp://ftp.oldskool.org/pub/misc/keyb/ Any advice is appreciated -- either that, or a source for more 83-key XT keyboards... -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/
