I have purchased a 1981 sunny coupe SGX a14+5 speed which is going into my 120y coupe, what parts can i get off the sunny e.g pedal box and brake booster that would be compatible with the 120y coupe

i don't know about the brake booster and pedal box but everything else should be good. pretty much grab anything that looks the same as on your car and stick it in a box out of the way because you never know whe your going to need it my box is now nearly empty but was quite full for a while there, just grab what you can. the seats might be nicer than yours, globes, fuse box. pretty much anything that can break on your car is nearly the same except maybe brakes and the like. it works out cheaper than going to the wreckers for a little bit that costs you $20 when you could have one spare

booster is good, i have a sunny booster on my car
