Biggest tire under a stock suspension dart????

I bet an adjustable pinion snuber would help.

I bought an adjustable MP snuber off of a fello FABO member. Plan on installing that at the same time I put the 3:91s in and the bigger tires on. My stock suspension is in great shape. Car still has original brake lines. Im the 1st to have it on the rd since 1973. Car only has 35K on it. Sat in a daylight basement since 73. Guy who bought the car new never made it back from Vietnam and his parents could never sell the car. I only got it after the parents passed in the late 90s. I made some people mad, because others had been trying to buy the car for years. rite place rite time.
