Is there a difference between a 69 sb and BB a/c Condenser? If so, who reproduces a correct unit? Same question for all the BB 69 AC lines...Thanks in advance.

The condenser is the same for bb and sb. The line from the condenser to the drier, and the drier to the expansion valve are the same, too.

The evaporator on the sb curves to the outside, and on the bb curves to the inside. Therefore the return line is longer for the b/b. Also the evaporator box (suitcase) is different. The bb engine is placed to the passenger side to make room for the steering box. Therefore, the inside half is scalped out more to accomodate.

I bought my evaporator and hoses from Old Air Products in Fort Worth. (817) 531-2665.
