Bought a new crankset yesterday for the old Rocky Mountain. Replaced the original Shimano 22-32-42 with same. The original was made in the UK, the replacement in Malaysia, and I guess the tooling is different. When I first installed the new drive side, the spacing was wrong so there was not enough clearance and the small (inner) chain ring contacted the bike frame. GRRR! I considered using a spacer, but instead transplanted the new chain rings onto the original body (Crank and spider? Chassis? Not sure of the correct terminology ...). Anyway, it all worked out OK.
Here are photos of new and old:
