driveshaft length?

[jeds320i]

i need to know how long the driveshaft is for an e30.. one with the 3 bolt flange that bolts to the trans and four bolt in the rear. im sure there might be more then one driveshaft but i swapped in a m50 into my e21 and has a getrag 260, i was just gonna mate the 3 bolt flange onto my e21 driveshaft but the wants $250, so i thought using just an e30 shaft might work somehow. it needs to be exactly 59 & 1/8" long, flange to flange. i noticed e30 ones have a slip yoke in them that give me some adjustability so i wana know the length. please thanks, Jed
