Keith,

In an ideal situation you could find an 1984-5 RX7 13B pa= n that does not have that

extra bolt hole in it as the mounts were still on the front cover.....= ......But since you

probably cannot find one I have a question.........Since I am not tota= lly familar with the

CCI mount plate is the spot on the plate under the extra oil pan bolt = open or would

you have to drill a hole for access to the threaded boss in the center= housing ?..........

I do not remember what the bolt size is (probably 12 or 14 mm) = but if this hole fits

flush with the CCI plate then a large headed bolt and copper gasket mi= ght seal it !!

FWIW
