Lew, I heard from Colby this morning, and he informed me he is not able to do any of the work I need done, due to the fire that devastated his home and shop. He figures you just forgot.
I heard from Mike Pranka at Dynavector USA, I asked him if an arm-lift assembly was available from the 502 MLk II. He said he'd have to check with the factory to see if the newer parts will fit.
I told him I looked at the 507 already, and it looked like the parts would fit. I told Mike to just order the parts for me, that I will make them work. I don't know who came up with the idea of using the parts from the 507, but I thank them for thinking of it for me.
Thanks everyone for your help, regards,
Dan
