grinding problems

well I dropped the 12a in my 83gs and it started right up. I went to push the cluch in and put it in gear and as I began pushing in the clutch something started grinding really bad. There is a cover plate that is missing from the top of the engine where it bolts to the tranny. When I would push the clutch in I could see sparks down around the flywheel. then the engine would stall out as if it was a load on the engine also the tranny wasn't in gear. When I tried to put it in reverse before the engine stalled it grinded reverse really bad and didn't go into gear.
Then as I kept doing it it started making the grinding sound less and less until it doesn't grind anymore at all when I push in the clutch. I can also shift into all gears without grinding except reverse. Also 1st and 2nd gears are hard to shift into. They don't grind they just don't want to go into gear when the engine is started unless you push really hard. 3rd 4th and 5th are easy to get into. Before the original 12a blew up in this car the tranny worked fine. Could I have shifted the angle on the rearend when I jacked up the tranny to put the engine in?

Another prob. This engine is out of an 82 with an automatic tranny. I used the carb off of my 83 engine and it seems that there is about 5 or 6 vaccum lines that I can't figure out where to hook upto. It idles at about 1500 to 2000rpm even when warm. and when I take it up the road it runs good and pulls upto about 5k but then It starts hesitating and is sparatic. Is there a good way to figure out where these lines hook upto?
Thanks guys

WOW, what a way to fix a problem, let it grind away, wonder what it was, and if it was important.

Just my $1.98..........

Throwout bearing

Similar problems as you described with the clutch in my Honda a little while ago. The engine wouldn't stall, but it would bog down a whole lot. I dunno if there were sparks, but you could smell the burning. The throwout bearing was bad. I needed to change the clutch anyway, so a new one was included with the kit. That sucker was one cripsy critter... The ball bearings in it werent even spherical anymore, a couple were missing, and it was all blue and rusty.

I'd check it out. You could mess up your input shaft.

Sorry to revive a two-year-old thread, but this is EXACTLY what the car started doing today. Nobody posted a followup so I'm curious if it was the throwout bearing, master or slave cylinder, or what. Any ideas?
