Old thread I know, but thought I would ask,
Does anyone have an old powertorque from the 80s that actually had one of these fitted? Reason I ask is every picture I have seen of these very early powertorques don't have one of these installed, and the mustang I got (84 model) doesn't have one either, even though there is clearly a cutout on the head for it, you can tell nothing has been in it, as there is not the slightest bit of wear, damage or discolouration in that area. You can see where the plug boot has been scraped though haha.
It is a pity they didn't use what they already had with the full crank and long ends on the bolts. Simple and effective, even when reversing out of a shrub.
