I had to dig out an old pair of 260's for use in our community layout this year. The springs are non-existant.
Can these be opened up by drilling the fasteners on the bottom & replace the spring, or am I better off with opening them up, cutting up an ergo floor mat and replacing the broken spring with the squishy mat stuff? I need them for a bump & go trolley and would like to prevent whiplash to the O scale riders....
Thanks
Roger
