The suspension works, I would long term like to replace front coil overs with Maximum Motorsports 12" 250 lbs. springs, replace the lower rear control arms, and do the Maximum Motorsports solid steering shaft. However, after replacing the anti-rattle clips that were missing on the front driver side brake pads I was amazed at how much noise went away. So this isn't as pressing, and will be fairly expensive.
The AC is an unknown, the fix could be cheap, or could be expensive. I also am always hesitant to turn the keys over to a random shop, especially with the belt routing for the Procharger, etc. That said I would like AC by next summer, as it limits when I want to drive the car.
The radio itself should be easy, with Crutchfield harnesses, etc. but then unless there is a component system where I can just unscrew, unplug, and replace speakers that might lead to a rabbit hole as well.
Really hoping the MM clutch quadrant kit, gets rid of my clutch feel/engagement issues, it was pricey but I keep seeing nothing but good things about it.
