OK, I know this has been covered before but I thought I would give you my personal experience to help someone else save some time. After reading many posts on this site I went ahead and installed some lowering blocks to the rear, simple and cheap, the rear was done. The front is a little more complicated. I cut 1 & 1/2 coils from the front coil springs and installed new shorter shocks. The stance was great but the ride was terrible. After 700 miles of slam banging I couldn't take it any more. Here is what I did today and it is sooooo much better. First buy a set of Moog 8542 coils. I got them off of eBay for $52.00 with free shipping from Jegs. Next buy a set of Monroe 555001 shocks. Nobody here in Indianapolis had them in stock so you will probably need to order them. I got them from Oreilys auto parts for $40.00 for the pair. The original cut coils and and the slam banging destroyed the original bump stops so I would advise installing new ones while you're at it. $32.00 with shipping from National Chevy Association took care of that. Now cut the new coils by 1/2 coil, that should take about 1 & 1/8 inch off the height of the coils. This not only lowers the car by about 2.5 inches and brings the coils up close to the spring rate of the original coils. I'm not going to get into how to install the coils. Get a shop manual or pull the one off the web for free. The job is pretty straight forward but any time you pull apart a 60 some year old front end it is a pretty greasy job but it can be done on jack stands with basic hand tools. Have fun and enjoy the way your car looks and rides.
