I have an 86 and run Bilsteins which are the same length for 79-04 using later spindles. With that said, I believe the sn95 struts are longer; shocks are the same. If you want to lower the car, I'd advise using the Fox length struts. Springs should be the same for both. Only difference will be ride height after installation - usually the sn cars are lower due to extra weight.
You may not know this but if you're using the stock 85 k-member, you will lose most if not all of your negative camber when combined with the sn95 spindle (must use 94/95 only). To recover some camber you will need CC plates but that wasn't enough for my car. I had to use the sn95 a-arms too (mine are 04 Mach 1s).
