Does anyone have, or know of a site, where the engineering drawings for Getrag transmissions have been collected.?? Have in mind drawings that will show the bolt hole layouts, lengths etc. I am trying to find a newer and more up to date 5 or 6-spd to replace my G76/27-5 (40 yrs old and 200K+ miles and no replacement parts) with a matching bell housing to tranny bolt pattern. Engine is an M110, car is 75, 280SL. Have machinist friend who could make new input shaft if necessary also willing to make new driveshaft. Any info appreciated.
