Proudwinner.....You can bleed air in the shock through the cartridge. What you have to do is pull the shock shaft to one side of the shock and you will see all the air and some oil escape. I use this method and it works well for getting the shocks the same.....it takes some practice but once you master it it works very well.
Dan O......You might want to look into getting the 99 hub conversions for the car that you have. The 98 had smaller wheel bearings and press on hexes as well as using a more off set rim ie the 185 rim I belive. Schumacher did sell a conversion set that gives you new hubs, axles and dog bones, bigger bearings(that last longer then the smaller ones) and hexes like we use now with the pin and rims with the correct offset. What I always ran on my 99 car was #2 hole pistons all the way around with 50 to 60 wt oil and blue or red springs and the shocks in the inner holes on the towers and that should get you started.
