We did it with this car.

It's a pretty easy swap. A steering column will need to be fabricated and that's probably going to be the most difficult part. You need to be able to accurately measure the pickup points to ensure you get the subframe in there square. If it's your first time doing some kind of chassis fabrication you might want to pass but if you are confident in your abilities there are certainly harder projects to undertake.
If you just want the 2nd gen rack and pinion steering the Bill's kit is certainly an easier route. We wanted to utilize some 2nd gen suspension components we also had so that made the swap more appealing to use. Also made the 20B install a simple matter of using the Banzai mounts.
