[TR] TR4 Hood Badge

[Don Hiscock]

Well, I didn't have my car for the first nineteen years of its life, and it
had apron bodywork when I got it.  Who knows for sure what was original to
its build.  TR3Bs are their own animal sometimes in esoteric ways the parts
manual doesn't always catch.

For example, the main gauges on every TR3B I've checked have "two piece"
clamps like a TR4, not the single U-clamp like a TR3A.  What's the SPM4E
say it should have?

Where TR3B rules are concerned, there are no rules!
