A guy called Scott has a '75 for sale in WI, $7500.00
Go to Search Tempest and do a search under Tucker Sno
I felt like calling but there is one closer to me in Vt.
that I may go look at this summer. Only problem
now is snowfall and land use. My hometown doubled since
I moved there in the mid nineties
I used to have a motocross grasstrack I put together for enduro cross
near the powerlines and could get my 426 into 5th, no more all built up now...
Tuckers are addictive, I remember seeing one roll by under while riding the chairlift
and marveling at the steel tracks revolving around the orange pontoons.
Only figured out how they work from this forum 20 years later...
Go for a rubber track / steel grouser type.
On edit : Just checked and there is one on craiglist Billings MN 1980 318 / Auto $14,000 OBO
looks tight
