I replaced the center bearing on my 65 C-20 LMC use to have the bearing support I don't know it they still do it's a one piece assembley bushing bearing and frame make sure you order the right diameter bearing they came in diffrent sizes.IIRC I only had to unbolt the rear u-joint (Make sure you wrap some tape to hole the bearing caps on the U-joint)the whole assembly should come apart real easey. L little tapping and some wd-40 to get the bearing off.
