Those look good.
Just an FYI, but I don't *think* the Thunderbird risers will fit the R3T. I could be wrong and I no longer have my R3T to reference, but I remember looking at it when I had my R3T and T-Bird side by side. That said, I would DEFINITELY go with the T-Bird risers if they'd fit before the Rivcos. I was never very happy with the Rivcos on the R3T. I had a good 1/2 inch of movement in them. Also, I ended up having to put locktite on the riser clamps because the two upper bolts kept coming loose and they were installed/torqued per the Rivco instructions.
