damien,

i see alot of guys getting the tgc spacers from topguncustomz.com or a similar product. they are a little different than the daystar ones as you can take the whole strut out as a whole assembly without compressing the spring and taking the strut apart. I may be wrong ( hopefully someone will chime in) but i believe the style you are looking at you need to take the spring out using a compressor and rest on top of the spring in between it and the upper strut plate. The tgc style spacers bolt directly to that upper plate and have 3 studs on top of them that goes into the upper strut socket. The tgc spacers are $91.95.
