Speedway has some
They dont come with the outer sleeve though, but its easy, you get some 1 1/8" ID .250 wall tubing and cut it to exactly 1.5" lengths (I paid a shop with a good band saw so they'd all be the same). We've made more than a few 4 links using those bushings. Jasons are nice too, but are slightly overkill. The speedway bush4es are made to do rear suspension on old doorslammers with big blocks, they will do minis just fine.
They also sell a front suspension bushing that uses the same ID pipe but is only 1 inch wide, so if you are doing custom lower control arms.
