It is 2.25'. So I would have to get a 2.5' glasspack correct?

What town ya located in down there?

Thrush glasspacks are better mufflers than the Cherry Bomb 'packs anyway...my opinion.
Thrush uses a perforated core instead of the louvered core in the CB. Less backpressure and the noise levels are the same given the same length mufflers.
The last pair of Thrush packs on my van lasted 8 years before they rusted away...good enough for me for the money I paid for em.

NAPA will probably have a few choices in the catalog too.
