Mike, wow, 28 years!!! That is an accomplishment in itself, so I have to say congratulations on that feat. Thank you for the compliment on my 67, as it's been on hell of a rough road, but she's almost complete!!
Hotchkis does have a complete TVS system for 1st and 2nd Gen Camaro's, however, it does not come with rear leaf springs. So, if I were you, I'd make plans to replace those as well. I'm not sure when you plan to purchase, but I actually just received a 25% off discount in the mail from them. It expires at the end of this month, but 25% is a LOT!!! I'd be more than will to give you the discount code, just send me a PM.
For ignition, I would go with nothing but MSD, and that includes the distributor and the box. This is a good time to buy from MSD, as they have a nice rebate going on right now. I'm running their distributor and the MSD-6AL box with the SS Coil. I Love that set up, and never once had any ignition problems whatsoever.
For exhaust, I'm a fan of Hooker SuperComp Headers and Flowmasters. In fact, Flowmaster has a new muffler out that is the Super 44, and it has a nice deep, throaty, muscle sound to it. I bought mine as a full kit from Summit Racing and installed it myself, then took it to a muffler shop to have it tack welded. In my personal opinion, for old muscle cars, you can't beat the way Flowmasters sound! Since you're staying mostly stock, you really don't need 3" exhaust, so I would just run 2 1/2" exhaust with either a "H" or "X" pipe. If you were going to build it, and try to push anything over 450 horses, than I'd probably step up to 3" exhaust. My ONLY complaint to Flowmaster is; they don't offer a polished stainless steel exhaust system like MagnaFlow does, and that really bothers me.
Wheels and tires, I run a 18X9 1/2 on back of Jade and up front she wears 18X8. The wheels are from Jason Rushforth, and are a little pricey, but they are so NICE!!! For tires, I originally ran BF Goodrich KDW's, as you can see in the pictures. I really love the flame design, and the tires handle awesomely. For sizes, the fronts were 245/40ZR18 and the rears were 295/35/ZR18.
The only thing that is not Hotchkis Suspension on my car is the Competition Engineering Slide-A-Link bars that I have on back. Other than that, she is ALL Hotchkis!!!
