67 rallye bezel with modern gauges question...

[Shmaako]

Currently my , now getting painted, barracuda has my DIY dash bezel installed and after much 'humming and hawing' I've decided she's worth more to me. I'm not completely happy with the results. I can take a second attempt but If I'm honest I've always loved the original dash on these cars, so I am thinking of buying a re pop from PG and installing newer gauge kit. However, I do not know the size of the original gauge holes..
Question is, will these 3 7/8" gauges fit or will I need to fabricate something?

Anyone know a reason why I wouldn't do this other than the obvious which would be to maintain original.
I would love to have everything original but not sure that is practical or how expensive that might be.

Don’t know if this helps you. I’ve got an old bezel and frame. Best I could measure. Not sure how deep the gauges your looking at are but that may be a consideration. Diameter might be ok with bezels on new gauges don’t know. Some of the reproduction bezel and original gauges for my Demon added. The ones you posted follow the original layout.

The instruments you linked appear to include housing, bezel and lens. They may not work behind the OEM bezel with dished lens and center cap. A member named @mullinax95 put aftermarket gauges behind the OEM bezel but it took some effort. I dont know how much butchering of the bezel and housing was involved. This was about 10 years ago so his pictures may be gone today.
It might be simpler/easier to buy it all from Classicdash.com 1967-69 Plymouth Barracuda / 1970-71 MOPAR A-Body Rallye Dash Panel - Classic Dash
You dont get the OEM chrome on the bezel. That design puzzles me. I can't see those 2 lower instruments leaving enough space for the headlight switch and wiper switch. I think some portion of the OEM housing must be used to support those switches. Only the flasher switch is mounted in the plastic bezel alone. Maybe first talk with someone who has purchased and installed this.
