OK i have a 4spd of some sort, i was told a OD, its has the long tail shaft, not sure if that matter's or not, but how would i find out?? if i posted some pics on here could you guys tell me?? i just want to make sure its a OD unit

Have you read this? http://www.slantsix.org/articles/4-spee ... speed1.htm

yes i have read that

Short tailshaft has only one mounting boss for the shifter assembly near the end (A/F body), long tail typically has two mounting points, or only one close to the front (B/C/E/truck/van).

O/D units have a bigger flange around the input bearing (where the shaft goes into the front of the trans.) @5.125". Also, the shift lever closest to the front of the trans. points down on an O/D trans., up on a non O/D.

That info and much more is covered in the article Josh linked to.

Yep just measure the front bearing retainer, IF its a hair over 5" then its OD. (if the shifter arms are not on it) If its less than 5" its a NON-O/D trans...

That is mostly true...but if someone wanted to install a normal A-833 into the OD Bellhousing, and swapped a Bearing Retainer from a 1976+ 3spd (like the A-230....Mopar didn't want to redrill the last of the 3 speeds so they have small bolt retainer pattern like the normal 833 and early 903/745...)...then the bearing retainer OD would be 5.125" and the tranny would be a normal 4 speed..
