Ebay has a set, https://www.ebay.com/itm/Jeep-Comanche-MJ-1991-Rear-Leaf-Spring-Plate-Factory-OEM/114616653289?_trkparms=aid%3D1110006%26algo%3DHOMESPLICE.SIM%26ao%3D1%26asc%3D20200818143230%26meid%3D2c00423a5a7b40a8919f3373f5442590%26pid%3D101224%26rk%3D3%26rkt%3D5%26mehot%3Dnone%26sd%3D114390700399%26itm%3D114616653289%26pmt%3D0%26noa%3D1%26pg%3D2047675%26algv%3DDefaultOrganic%26brand%3DJeep&_trksid=p2047675.c101224.m-1
Also, you could weld on a new peg for the shock. I bet you could get a set from a junkyard for $20 bucks or so too. Facebook Market Place has a lot of Comanche part outs so you can prolly get a set there too.
Hope that helps and that is what your talking about
