Does any know if the arms that bolt to the block and extend out to the motor mounts are the same for the M127 SL engine as the M130 983 engine. I have a set of M127 "arms" that I would like to use with an M130 engine for a 280 SL. The "arms" i have for the M130 engine are from a sedan engine and I understand that they will put the engine up too high in the engine bay. Many thanks in advance.
