my ultimate goal is to convert a 2 door Ea81 coupe into 4sp. d/r.......when i do the conversion will the mustache bar / rear frame bolt right up or do i have to drill some holes?

Well some have said you'll have to drill holes, I have personally a 86 std 2wd hatch that already had the holes and nuts there in stock form. Best bet is to get the car and see. Aparently they are not all the same...

More than anything you will have problems with the transmission tunnel. It's not big enough to accomidate the 4 spd - 5 spd is even worse. Lifting it or beating/cutting the tunnel will be required.

 

You will have to change the complete exhaust system, front sway bar, and fuel tank.... as well as the rear end. Front strut's are different too.

 

It's a lot of work, and I probably won't even do another one. Waste of time - the coupe has the same wheelbase as the wagon and virtually no storage space for off-road.
