all

we are going to replace the '$5 dollar shop' static belts in a '72 911 E coupe and would like to know which are currently the best/most convenient to use and install on a street car
we have been pointed in the direction of 944 belts but want to check the best options before buying & installing
Porsche belts are preferred as are the top release buttons
has anyone done this excercise recently ?
we have some pics of the mounting points but would like more info
also anything to avoid ?

TIA
Dennis
