I'd put new mount bushings in, while it's out.
where do you source the new bushings for the divorced transfer case crossmember mounts?

These are perfect replacements for the OEM rubber ones. I bought 205 bushings for a Bronco of that era, and they did not work. These do. Thanks goes to user KurtfromLaquinta on RCC; he;d used them when he rebuilt his 1974 W100, and they worked well for him.
