Hi, new to the forum. I am going to be doing a 350 to 200-4R swap soon on my '72 Cutlass and in an effort to save money where I can, thought I'd check around ot see if anybody on TB.com had either the ATSG manual or the CK Performance manual they wanted to get rid of. I'll buy new if not, but thought I'd check here since this is the undisputed center of excellence for info on this transmission. Thanks - mark
