I've had an IROC box for about 2 years. The feel of the box in my 68 is very similar to my 87 IROC, but still isn't what I'd consider a perfect solution. It's definitely better than an original PS box or a manual box (what I converted from). I got mine from Rock Auto and ate the core since I didn't have one to return. In my case, I used AN o-ring adapters rather than using the Lee Mfg kit. If you do a search online you should find a site that tells you what Help! (Motormite) rag joint to order that will adapt it to the factory column. IMHO, it's a great lower cost solution to improving the steering on a 1st gen Camaro (and others).
