1941 thru 1947 overdrive driveshaft

Does anyone happen to know how much longer the overdrive trans is than the regular 3 speed?  if you know the length of either that would help me - I have 5 driveshafts laying around but they are all too long.  If anyone has an overdrive driveshaft for these years cars and can bring it to the national, I would purchase.  Thanks in advance.

Would it matter if the donor car had been (for example) a LWB?  In other words, were the "overdrive driveshafts" for some models longer than the overdrive driveshafts of other (shorter) models.  Just a-thinkin'....
