D44 Q's i cant find any info on my axles

I recently got a pair of axles off of a 78 bronco but everytime i enter the numbers on google to find out my info i get turned down lol. for instance my numbers are 620072R 449F and i cant find anything except some forum sayingford doesnt make those numbers that high only 60..... or 61...... no 62 numbers the other numbers on it are C38610 Driver S and C38609 Passanger S. the tag on front has a 3 50 D8TA-BE ...610047-9 if anyone can enlighten me on what i have here i would be greatly appriciative .....so far i believe they are dana 44's high pinion reverse cut but idk

Front sounds like a run of the mill d44 high pinion reverse cut with open 3.50 gears. Rear is probably a 9 inch.

That's what I thought too its just kinda scary not finding that info on the web ya know plus I need to just pull it apart and take a look for myself no tellin what someone else has done in the past. Where should I go to find the cheaper deals on my gears and lockers
