Hi David,

It depends on what your definition of a "mounting kit" is.

The typical manual transmission is the B/L 5 speed from a TR7/8/SD1, but 
that is not a straight bolt in.

Yes, there are engine mounting brackets, transmission bracket, power 
steering bracket, modified shifter bracket, etc to purchase from the 
UK.  The brackets are pricey. 

But you need to know this is not pull the old engine and bolt in a Rover.

The short list is:
-Lengthen the drive shaft 4";
-Shorten the transmission shifter housing and shifter rod;
-custom make speedo cable end at transmission (larger pressed square end);
-purchase proper transmission speedo gear or purchase a speedo ratio 
matching gearbox;
-modify radiator ports for 1.5" hoses facing rearward;
-recore radiator for 3 or 4 row high efficiency;
-source proper short nose water pump with fan pulley;
-custom measure and buy alternator belt;
-custom measure and buy power steering belt
-move the radiator forward 4";
-install TR8 style expansion tank;
-custom make radiator hoses from several different radiator hose bends, 
or put crappy flex hoses on;
-custom make heater hoses to heater and to heater control valve;
-make custom power steering hoses;
-relocate PS pump to left side of engine;
-lower subframe cross member 1";
-lighten front road springs;
-machine intake manifold to lower the carburetors to clear the hood or 
install EFI  system from a TR8;
-Manufacture custom exhaust manifolds to clear the steering link, or use 
block hugger tubular headers (4 into1), then shift the down pipe 2" 
rearward on each side, make up custom link pipes;
-custom make wire harness to new alternator location and probably a 
Bosch/Motorola/AC Delco unit.
-custom make clutch hydraulic line for UNC thread at Master Cylinder to 
Metric thread at the TR7/8/SD1 replaced slave cylinder;
-remake new wiring harness from old starter position left side to new 
starter position on right side.
-remake new wiring harness connection for reversing lights, transmission 
switches

That is the short list ...

Do you want to hook up the AC?
-add short radiator condenser;
-install electric 16" pusher fan and 15" flex engine fan;
-add thermostat controller;
-make up custom barrier hoses;

I probably have the long list around somewhere.
Cheers!
