Werner: What size and shape oil can are you planning on mounting under your hood?
Here are some other examples of oil can brackets for various shapes and sizes of oil cans. I use them to hang/display oil cans on the walls of my petroliana room:
....for a round can:
....for a WWII German military oil can:
....for a 2 Ltr Texaco can:
....for a triangular Shell can:
....or this different version for a triangle Shell can:
....for a triangular Gargoyle Mobiloil can:
....or here are a bunch more for mostly 2Ltr oil cans:
.....and some other's again for 2Ltr oil cans:
...or you can just purchase (on eBay.fr) a new 2Ltr oil can support in France for a VeloSolex and just mount that under your hood somewhere:
Hope that helps and gives you some ideas,
