I have an '81 cj-7...formerly 6 cylinders, temporarily 3 cylinders (or a sum less than six anyway), now almost an 8. I'm looking for the brackets that go between the block and the rubber motor mount on the 304. Apparently the brackets from a wagoneer/cherokee/J-series will not fit the cj frame? The swap stands still 'til I find a set. Anybody have a spare set?
