I think all aftermarket radios will require some sort of installation kit to take up the gaps and look clean. That is unless you can find an aftermarket DIN 1.5 radio, which would fill the cavity completely. The only way to stay "looking Factory" would be to retain the original radio and maybe have it serviced to perform at it's best. There are some older model Pioneer DIN 1.5 radios available on ebay now and then. I tried to grab one but was outbid.:frown: I ended up just going with a regular sized Pioneer radio and the fore mentioned install kit. I think I got it at Walmart and the box said it was for 84-87 g bodies (olds,buick,chevy). It was available in a wood grain and plain black plastic.
