1966 4X4 Transfer Case question...

[CaptCanuck64]

I have a 64 Pickup on a 66 4x4 frame and there is a lot of movement in my transfer case to the point it binds up the U-Joints. I definitely need new bushings for the transfer case mounts. I've seen the kit for sale online (here's one of them - http://www.autopartswarehouse.com/sku/Chevrolet/K10_Pickup/Prothane/Transfer_Case_Mountapwcid=ecncse&ID=apw1966chk1pitrcamoPTH71603BL. Any other recommendations for these bushing kits?

What I'm wondering are the rubber (Polyurethane) parts the same for the top (driver) mount and bottom(passenger side)? If so, I'd need two kits.

Also, looks like prior owner had a piece mounted to the lower (passenger side) bracket and to the frame(see pic). Does anyone think I need it to be re-welded? I'm thinking no.
Thanks!
