A75 - code name Mitsubishi Colt Lancer !! Nothing to do with A175 kotak besi...This is the accester or first generation of Lancer & (this version also the first have 1.8 Turbo GSR)
this car started around 1972 to 1979 if i am correct..different spec and face lift..
My dad used to have 1 and been drove it for over 20 years..got it sold off in year 2009 only

...(sold as the price he bought in 20 years ++ haha since its superb well maintain and 95% stock standard)
Part wise i think 1st generation saga quite compatible to it..since my dad lasttime masuk Saga brake servo ( i think only mod the mouting braket..no need ketuk here there)...engine i heard his mech said like old saga 4G1x engine can masuk (dunno plug and play or not)
My dad sold it off reason being part quite hard to find and expensive (japan obsolete long ago)..only spare part shop that kept old stock (which is not many have )
