[CR67rep]

So yesterday I went to find a new air filter for my CR with a 350 Chevy. Apparently I have the unicorn of air filters, it is an oval filter and measures 12" long and 9.5" wide with overall height of 2.5" (2" being actual filter element). The only 12" oval filters I can find after an extensive search online are barely over 8" wide. The current filter has no brand name just says Model-351 (no help so far on my online escapade). The air cleaner has a top plate that says Cobra, but I have no idea who made it as it is much shorter than a true Cobra cleaner assembly. I'm almost to the point of replacing the entire air cleaner, although I'd prefer to spend ~$25 on a filter instead of $100-200 for an entire assembly. Any help would be great!
