A500 42RH Crossmember template?

The spool mount was a lot easier to modify, but it does extend a little lower than the biscuit type.
The only place in the floor I had to mod was the hump brace and a 1inch round by .5 inch deep dent in the floor where the fitting off the governor port is for the pressure switch's line fitting.
Inside the car that dent is a very small hump between the seats. (not noticeable at all under the carpet even if you know where it is)
