35-36 Ford rear shock mounts

I think I've seen an ad for shock mounts that fasten somehow to 35-36 rear radius/spring hangers to mount tube shocks. Does anybody know about these? Dave, 636 861 7376 or oconrad32@gmail.com. Thanks

 

The ones I have are from a 47 . They bolt to the stock backing plates on a 40 rear end. ( or any early ford rear end with 3 3/4" radius rod bolt holes.) so-cal sells them but they are $150 or $160 a pair or something like that. The p*** side on an original 47 has to be shortened 3/4" to match the other to.
