Bought a Crenlo cab that came off of an 820 Rice special that had very low serial# for an 820, it looked like an 80 but painted like an 820 but had small fenders like 80. It had 23" tires and serial# plate indicated it was 820. Was the Crenlo cab supplied as original equipment for the 820 by Deere? I bought the cab to put on my black dash 820. Wonder if cab will fit the big fenders and was floor board the same on early 820 as on later production, because channel iron on bottom of cab seem like they are too high and I would have to cut knotch in my 820 floor board. Appreciate any comment and advice, Thanks ...
