Here's a good one. The Alan has a 6spd Uniglide cassette on an HF-6207 Shimano 600 freewheel- the one that comes off with a tool with 2 tabs on the end. Will an HF-6208 freewheel and cassette fit on the same hub? 6208 takes a circular splined park tool freewheel remover. Wheezing Donkey i'm looking in your direction
