Replacement rear suspension fork bushings 1983 Marathon

[cvhsquared]

I just picked up a 1983 gas Marathon at an auction that was listed as inoperable. Got it home and put the rear end on jack stands and jumped it off the car battery, started right up!

Drove it around and there are a couple of loose items in the steering and suspension. I have seen the steering box parts on several websites along with shocks to fit this lift kit but I can't seem to find the bushings that connect the rear suspension fork to the main frame at the bulk head under the seat (bulk head is where the F/R switch and ignition are). There is alot of slop in these bushings. Anybody know where to get these. My rear has coil springs not leaf.
Thanks
