servo i.d


can anyone tell me how to identify 200-4r servo's ? i have heard that the gn and monte ss servo's are the best ones (as far as oem) would like to find one of these and i have a trans parts source but need to know how to identify so i know what i am looking for. is there a number stamped on them or do you just visually tell the difference if so anybody have pictures or numbers ?
The Monte should have a 692 number while the GN should have a 694 number. The Hotairs and other "performance" cars got the 692 which is the "medium" sized servo. The 569 is the smallest and the 694 is the largest. Hope this helps.
