I installed my trans blanket by using the rear intake manifold bolts for the straps
I have a trans temperature gauge and I haven't seen a increase in trans. temps so far my balnket is the universal RCI and it doesn't fit real tight on the Mopar after market large sump steeel trans pan
My motor is moved back one inch on the trans mount in my 1971 Duster (it has front elepahnt ears also) so the trans in closer to the body than most, in fact I have to drop the trans down and remove the front elephant ears bolts from the frame to get the trans in and out of the car and to install the blanket easily
I bought the CSI carbon fibre trans sheild firstand ened up buying and using the blanket
