Update... all the decals EXCEPT the air filter and 'early' round oil filter decal are done.
The decal shop sent me some questions regarding the colors, and gave me a initial quote. The 'early' filter decal may not happen. The deep sump oil pan decals take up A LOT of real estate. They are sending back a layout to let me see what I have left.
The decision is:
I have little to go on for an air filter decal. The air filter decal was pretty much standard through the production run. But anything I put together would be 70% accurate.
The early round oil filter decal is easy to figure out, but would only apply to a smaller subset of vehicles (well, anyone could put it on, but its only correct for up till about mid-42).
I am leaning towards going with the air filter decal as it covers more vehicles, and would be more 'prominent' when looking into an engine bay.
Anyone have any feedback... you can PM me it you like.. I know a lot of folks don't like to be seen posting on this site.
