The profile I used is a 45MM hole with a 2 3/4" stack HT. This is the best for a 5 liter engine. There may have to be so minor tweeking to some.
Mike, If you have the hole size and the base measurements then I can have it made to fit. The best way would be to send me an old one. That way I can laser measure it and it will be perfect.
Rick, That hole can be cut to any size needed to fit.
