Sleep on your decision for a week. An opinion from me is just that, an opinion, largely based on income. I would leave it. I always liked the multiple disc clutches I've had in other cars of the era. The "plates" don't need resurfacing, only relining. Only the pressure plate, if needed, can be resurfaced. The driving and the driven disc pins on the spider may be worn, they can get grooved from the plate discs. Center spring can get weak. I would first locate a parts source for this clutch before you dive in. Disassembly/assembly needs to be followed closely for they can be killers with that main spring.
