Frankie has run them for a year with no problems at all. Great - but a little voice says "what about the NEXT time you get your foot in it?" It's like being pregnant - you either are or are not, and it happens all of a sudden.
Post 9 and Post 12 say my old ones are interlocking. Post 15 says they are not. I am learning as I go, but if we look at the first pic I posted, there is a slot at right which presumably goes over something? (The mounts are here, the motor is at our other place 20 off miles away so I can't verify). Anyway, at the LEFT of that top pic there is a metal tab which looks somewhat like a flat "T" which I'm not seeing on the 2249 mounts. Do the slot at one end and T at the other end constitute the locking feature?
It appears my two options if I want to keep the "boomerangs" for the wires are 1) use the new 2249 non-interlocking mounts and hope they work as well as Frankie's have so far, or 2) examine the old ones, and if the metal is solid and only rubber coating is gone, put them back in.

I would
The FLAPS is having them brought in, but I said I was not going to pay until I can compare them side by side.

I have the boomerangs on my 63 and the interlocking mounts. I cannot remember if I notched the tin (it was 1988) but they can easily be made compatible.
If you have seen what can happen when a mount separates, you might have a clue to the reason GM standardized on the interlocking style.

RRman I'm sorry for the confusion. I said yours weren't original replace them. Yours are definitely 100% interlocking. I was addressing Elwood13s post13. His are the early noninterlocking. And they will interchange. To me as everyone else has mentioned, it's very unsafe to not have them.
Also Elwood13 sorry for referring to you as Ed. I was thinking about Emdoller when I typed that.
