Thank you all for your bits of wisdom. I see you say "if you want to" does that mean it is not necessary to use the boot/spring retainer if I don't want to drill & tap? User 64conv65hard suggests I can un-mount the single pot and leave the push rod in place and just drop in the new?
If it isn't clear I have never messed with an MC before so I am just trying to plan out as much as possible before I disable the brakes in the car for the swap.
