I don't know why it was changed and my fear is that (per the catalog) the 13347200 is for 8" wheels.
Does anyone know the physical differences between these two forks?
Can I perform the desired conversion with the parts I received?
I contacted SIP, but they just sent me links an offset Shock Absorber plate (17480700) and a mounting kit PK50 (J9012600), which looks like it contains 8" wheel parts, as well as some redundant parts.
There wasn't much explanation.
