I had a sunny it was an 80 model with a CA18DET 5 speed hilux diff and 11" ford ventilated front brakes .The autometer boost guage fits perfect in place of the old clock the 3/3/8 series tach fit in place of the old tacho but these days you can get your instruments modded for different signals , hilux diff was a 84 model stock width I ran toyota camry FWD offset rims on the rear and EB falcon rims on the front as it was the correct offset as I ran hubcaps anyway was all 5 stud ford pattern anyway. I also changed the fuel tank to a pulsar one so as to fit a better exhaust it was 3" mandrell bent all the way , actually still have it if you are interested , and still have the spearco cored intercooler to suit as well check my pics for the sunny not the best as they were scanned in but that was almost 12 years ago lots of fun , blew away many cars as who suspects a sunny .
