just to clear things up...a hatchback looks like this:
and a coupe looks like this:
The dash is honda but the dials are rover, Rovers, in the UK at least, run 130mph and 150mph but Hondas run 120mph and 140mph.
You can buy el gauges for Rover speedos I can tell you one place in the UK that sells them. Are your gauges mph or kph?
If you have a coupe then it's a tomcat, any coupe is a tomcat as it was just an unofficial name.
clutch and exhaust is probably going to be a bit too pricey to send but can check if you want.
