slotted material(suitable for a Randall) is not similar in dimension to non slotted material
BUT...if your going to get a shop to cut the "slot" I'm sure they could do the rest of the forming
I gave my last orange slotted away....right??
then, when I needed one....I ran across a generous fellow that visits this site on occasion that reciprocated my kindness....what goes around....comes around
