Latecomer to this great thread. I don't know if it is relative to the subject but I have a 75, 280Sl, which means the 110 engine, with a Getrag 5-spd manual G76/27-5 or 717.00. To the point, the tranny has a removable bell housing, part # 115 250 69 05 with built in bosses for the slave cylinder that is still available from MBz. $265.00 thru MBz of Annapolis. Might be a good starting point for a conversion?? EPC says it fits a lot of other models beside the 107. Have no idea what the bolt pattern is. All the necessary additional parts, throwout arm and bearing, slave cylinder etc., are also available.
