Hello again! I went out and bought a pair of the 16.5" Wheeleez dolly wheels and found the width of their hubs are 1.5" too wide for the SS extenders I have on the dolly. My boat came with the large Florida Sailcraft jet ski wheels with 1" diameter centers and the extenders appear to be the 9" variation. In an attempt to free the extenders, I found the are "welded" to the alum axle. After generous applications of PB, no movement. What can I do? I don't have much in the way of shop tools here.

Thanks in advance!
