Yes proper booster is a 7-1/4 inch unit, they are rebuildable from Booster Dewey. There is also a 7 inch unit that is not rebuildable. The larger units were first installed in 1973. wave

The difference is there is a removable band around the 7-1/4" like Scott shows above. The 7" is crimped together.
