The 47-53 truck switch has a stamped sheet metal mounting bracket. to hold it in place.
The 54,55-1 switch has a stainless bezel nut to hold it into the dash, in pre-notched slots.
Pretty much everything about the 54 dash is different from 47-53.
Thd rummys on ebay are just generalizing, which screws it up for most of us, they really dont know what theyre selling.nTheres 3 or 4 different switches that they just have lumped into
one , and who gets to pay the return postg?
When the listing tells you its "naturally aspirated" ?for an ign switch? I sure as yell aint shopping there
