Do you have the "4 speed hump" already?
Yes its a factory 4-speed car.
If the crank centerline and back of flywheel dimension are stock or close I think it should fit right in if the shifter was set up for your car.
I put a TKO 600 in a '70 California built E. Besides the 4 speed hump the front of the tunnel is tight on these and I added a relief piece per instructions. It did take a custom trans cross member supplied as part of the kit from Keissler (new owners Silver Sport). The shifter landed right where it was supposed to and I shimmed the transmission mount to dial in drive line angle with OE rear.
No issue normally with tunnel front on B's that I know of.
Hopefully it fits right in.
