Reply to "Valve cover emblems & now extensions (11/24) update"

OK, another valve cover question!

I know that on the air injection engines (smog pump!) the spark plug tabs on the V/C's were fitted with the factory "extensions" to keep plug wires off of the hot air injection rails.

If you did NOT have air injection, did those extensions still get used?????

I can't find enough pictures to see a trend at all. Those extensions were only used on 1968 engines AFAIK! 69 engines generally didn't have air injection on production Mustangs, only with the Boss2 and the 428CJ.

I want to put my emblems on.....but need to understand if I should or shouldn't put the extensions in place!

A good picture of a LH (driver) side extension would be nice too! I only have pic's of a RH version....and only a RH version in my possession!

Pics of attaching screws would be nice.

Once the emblems are attached, it appears like there isn't enough room to slip the stock plastic wire organizer/retainer in place????

In pic below, top bracket is for RH V/C, correct for Goose.
LH bottom is a 67 410 version, RH bottom is a 66 Lincoln 430 version.

I would like to know if either on the bottom are close to proper for LH V/C??? (or was one even used?)
Cheers!
