Two new bearings in each wheel and four new seals really adds up x 8 wheels and two idler wheels...the wheels all had the plates welded on them to prevent anything being jammed in the spokes, even though the wheels were NOS years of sitting had rotted the plates through in many spots so they all had to be removed and replaced. I had considered leaving them open once they had all been removed but then opted to make new plates and re-install as original. One thing I did do was to laser cut the plates out of 1/4" steel instead of the original 3/16" ...figured they would last forever with the slightly thicker plates
