Okay, nothing goes right for me it sure seems.

List of new things:
Euro E36 6 Speed
Shortened Driveshaft
Shortened Linkage
UUC Performance Organic Clutch Kit

Got the 6 speed installed, everything bolted up, turns on no problems.

I run through all of the gears in the garage and let the clutch out slowly with the parking brake on - All gears operate as normal.

I put it into reverse to back out of the garage, no problem. I get into the street, click it into 1st gear, take off normally.

Get up to 2500rpm, shift to 2nd gear - No problem.

Get up to 2500rpm, shift to 3rd gear - Gears grind like crazy, will not engage 3rd gear. Skip to 4th gear, works fine (usually, had a grind once but I think that was just because I was angry and being a punk).

Have not tested 5th or 6th.

When downshifting from 3rd, will not engage 1st - even at a dead stop.

Am I SOL (and $$), is the clutch not installed properly, are the synchros all destroyed?

I dunno. I'm sitting here with a lot of shortened parts and a car that I can't drive, and I'm literally about to cry - right after I break everything I can get my hands on

My gut says, I can either learn to drive a car w/ no synchros or spend a lot more $$ and put the 5 speed back in. Anyone else have any ideas?
