90 degree oil filter adapter

[jeepguy1948]

I have ordered a oil filter kit from Mike's. I would like to install a 90 degree adapter to change the filter mount from horizontal to vertical. The problem is that the adapter is dang near as expensive as the whole kit it doesn't seem to me that one of them should sell for $135 (approx.). I know that they were installed at the factory on some mustangs and such but I can't find a used one. Any ideas?
