Doing tools the other day and saw the difference. The one on the top came out of 75-76 kit. It is almost twice as thick as the early one. Just an side note that I am passing along.

Stamped vs cast it looks like? I had to sort of build a tool kit for my 914-6. Combo of 914-4 and a few 911 tools. I snagged a 911SC lug wrench, it was cast.

Both were cast

01/74 build 1.8 for you.
orig tool kit came with car back in 89.

given what we have been tracking with changes in 74 could be one of those obscure trivia details where the tool kit gets changed somewhere mid to late 74 before 75?
