The "M" Pump is off a 617 NA. I don`t remember if it has 2 or 3 bolts that mount it to the engine. But I think it will fit as Sirnik84 put one one his 84 SD, but it was doggy because it doesn`t deliver the same amount of fuel. He swapped it back to a "MW" Pump.

Wouldn`t it be easier to just swap in a new/different Primer Pump? That is if you have one. Be hard to source one today.
