Welcome to PP. Just to let you know, there are absolutely ZERO aftermarket lenses for our cars. All "aftermarket" taillights are custom made. Your car will have the clear over red. The 88-89 yellow/red rear lenses will not work without time, money, and energy, not worth it. They are no longer being produced, so you will be limited to the For Sale section at the bottom of the forum, Ebay, Craigslist and junkyard.
Strongly recommend searching this site on information about your engine before you do any upgrades. Another thing, the B20a/B20a5/B21a1 are unlike any B series engines, no parts for a "B series" engine are compatible. And I don't know if you know, but DO NOT rev over 7k rpm or you WILL send a rod through your block.
