200-600mm bayonet mount sloppy. very very sloppy.

My Sony 200-600mm  had a "loosish" fit when mated to my a7R3 and, on my R4, it is amazing it does not leak light, it is that sloppy, obviously a buildup of out of or nearly out of dimension tolerances. Does anyone have any experience in changing out the bayonet mount on this lens ? The replacement part as noted in photos appears to include the electrical interface, which is my biggest concern going in. is there a connector or a soldered connection ?

I am mechanically competent, but I do not have a ton of electronics experience, thus my query

TIA
