I've found Legacy BC2 MY92 1.8SPFI 5MT FWD - body's in a nice condition, without rust, never been in any accident, but engine is almost dead, 4th gear is noisy, so I'm just going to throw away all the tranny with engine and get 5MT 4WD pull-type-clutch gearbox and rear diff (from GC8 typeRA), also I have all the mountings and all I need is propeller shaft. There are a lot of p.shafts here in my regional autoparts markets, but no one of the sales managers could say if the certain shaft will fit my transmission, though they are marked as "BC5 MT". I searched through service manual for BC/BF Legacy and found that front part of the shaft must be 21.57" (548 mm) length from one U-joint center to next one, but no one of the shafts I've measured in markets fits it.
Searching for certain measurements on the internet - no results.
Any help from 1stGenLegacy owners would be appreciated.

I just need actual length for front and rear parts of the shaft
