I have been very happy with Monroes for street and mild/moderate wheeling (no pre-running or jumping, though). The series I put on my '88 probably 10 years ago used to be called Gas Magnum Plus or something like that. They still sell the same shock but now call it something else, and to further confuse the issue, if you buy through Advance Auto they have their OWN name for that seriies. I don't know if that's also true for the other stores in the Parts America chain.
I believe they are now called Monroe-Matic Plus or Gas-Matic Plus. They sell for around $29 each and have a lifetime warranty. Mine are more than 10 years old and have probably 120,000 to 140,000 miles on them and they still work fine and ride well.
