To convert an automatic trans engine to a Manual requires a bit of work

Pictured on the left is the original 220SE flywheel with segmants removed to match the rotating balnce of the drive plate on the right. .A lot of material had to be removed . The reason the 250SE engine vibrated itself to death was because this simple job had not been carried out.

  it’s a bit hard to see here but the gear lever is that little thing between the seats.
