A nice fella on Craigslist hooked me up with a pair of '99 "tall" springs, paint code yellow/red. (The yellow looks a little green, which was confusing when doing research on springs). Gave them a little wire brushing on the ends where some surface rust had set it and primed/painted.
Old (yellow/blue) vs. new. Note the extra wrap.
Bumpstop clearance before and after:
The mod netted me a clean 1" at the rear wheel wells, and my bumpstop clearance went from about 1/4" to 1-1/4", much more comfortable on the bumps now!
Bilstein 4600's coming next week...
