'87 FC Air Filter

[one_dusty_hoot]

The manual for the 3208 Turbo states a WLPN 3734191 or
Donaldson P12-9396 as a replacement air filter. What is
installed is a Wix 546848 which crosses to a Napa 6848.

Napa want $152.69 for these filters.

I feel they are made by one mfgr. then branded, maybe not?
Does anyone have another cross number?
Are there any used by BB outside the '87-89 FC?
