that I have. I got my 205 out of a 72-73 ihc scout and when I did i took all of the mounting apparatus and between the two was pretty easy to install. I had a 205 out of a dodge also which was in better shape than the ihc one so I rebearing that and used the ihc yokes and that was it. it mounted in on the same angles as the t221
I would imagine that the mounting from a 1000 - 1200 ihc in those years would be the same. they may have had the 205 in a few years prior to that also. you may have to research that
if you can get a r/hand drop 205 case, I believe that you can take everything out of a l/hand drop t/c(eg. ford) and drop it in
