I have a 71 hideaway grille and all the brackets, motor, rod, and even the shorter headlight pedestals. I know this has been covered before that it well fit into the 73/74 bumper. I was wondering if installing it well help with the front bumper gap as I would be loosing the 3/16" bumper inner support bar reinforcement that runs the width of the front bumper. I have noticed in other threads that when elongating the 73/74 bumper brackets notching the front frame or removing the metal flap and grinding the frame down to the nut cert was necessary. I was wondering if it would be still necessary with using the 71 hideaway set up since my bumper would bolt directly to the y brackets?
Thank you to anyone that has information on this!!

The hideaways setup has nothing to do with the fillers setup. You can live with the hideaways setup on the stock 73/74 setup with fillers or remove fillers and get the bumper sucked in to the body if you want.
Structurally A 71/72 bumper is exactly the same bumper than a 73/74 with just the corners welded provisions for the fillers on lates. But ALL got same provisions for both setups, non hideaways and hideaways setups... just the extra bracketings setup for one or the other will make the difference
Pretty sure the shortened headlight pedestal are not necesary if you keep the bumper fillers. I have known lot of ppl who has made the conversion even in 71/72 still using the non hideaways headlights pedestals, maybe tighter but still some room on them. If you remove the bumper fillers and since you already have them won't hurt to change those, but keeping fillers I don't think will be necesary
This is not personal experience, but lot of years checking for this setup change and experiences posted on the web.
The frame rail notch job is not necesary either, unless you want bumpers EVEN MORE close to the body. If your will be driving the car, I wouldn't do it. Road vibrations and bumps can rub the bumper with body. Keep some gap won't hurt the look for a stock look at least, kinda 71/72 got.

okay thanks! I won't notch the frame at all which I was not really wanting to do. But I still should elongate the bumper bracket holes some to slide it back some? I am okay with some gap.. I have 72 rear brackets for the rear that well leave 3/4" of gap Kind of want to match the gap on the front bumper. Thanks again for the information  |

Yes, elongate the holes is a must. Dunno how much. Bob here made it on his former 74 SE
