is the gas neck made of steel?

AND TO ANSWER YOUR OTHER QUESTION ABOUT USING STEEL FOR THE NECK, THATS ALSO A YES, GAS IS OBVIOUSLY OIL, SO THERES NO NEED TO WORRY ABOUT RUST WHERE IT COUNTS.

Thanks for the reply ^^^ I love your four door. Do you have any more info, photos, and details of the build, especially the suspension? I am prepping my four door to drag a modest set of wheels with thick rubber and love to see others set ups for inspiration

mine is steel, ive cut it,extended it and rewelded it. now located in the trunk, it works good
