Just installed a set of Pioneer model TS-A6965 in stock location on my 86.These are 6x9 two ways.I purchased them from Best Buy for 79.99 and bought the adapters there also.They fit with no probs.A three-way is going to be much harder to fit.I went the safe route.They arent going to win any competitions but they sound a hell of alot better than the blown 4x10's that were in it.
