Does anyone know which one of these bolts is correct for the heat shield on an E Body?
Thanks in advance and Merry Christmas

i just removed an original dec 69 built l.a challenger shield to fix the sender float and the bolts on that were longer with a self cutting end like a tex screw-they were 7/16 head with 1/4 unc thread about 1 1/4 long at a guess. if this question was last week i would have taken a picture. if no one else chimes in with a pic i`ll see what i can do. shields were also installed prior to proof coating.

Thank You Frank

how about these : fastener

The one on the right side.. Left one looks like the bolt for fuel/brake line clips and rear sway bar brackets. But hard o see from the fuzzy pic.

next week i will get the car back to photograph- definitely original bolts but they had a drill type end different to the one linked by furyman-might be an l.a.plant type bolt thing.
all the best
