I used repops on my 67 from BEA parts. See pix #4 and #5 below after I restored my 67 dash. Yeah I paid dearly for em, and had to work em a little bit to fit. The one I got didnt have the little dent defects like 340man showed. I did have to trim a slot in the top for the metal upper reinforcement to fit like oldmanmopar did
However the plus is that the chrome on the repops is NOT vacuum metalizing process. Rather it's the same process used when they chrome plastic car and truck grilles. That holds up really well to the elements, and will not come off or get dull spots in it from using windex on your windows. Chrome will stay looking good for decades.
You have really 2 choices keeping a rallye cluster. Both options are pricey.
Option #1 If staying with the OEM rally cluster, pay big dollars and get your OEM one vacuum metalized again, and deal with spotting, dulling, and fading on the chrome over time.
Option #2 buy a repop which uses actual more durable chrome plating over the plastic, make it fit, and not have any chrome issues.
Or the 3rd much cheaper yet very good looking choice I am making on my sons 69 dash.
Option #3 The route I am going with on my sons 69 notchback. Painting the plastic bezel matte black, and using carbon fiber look upper and lower inlays I bought from Jim over at DMT. I asked him make the lower center dash trim without the cigar lighter hole and without the radio hole kinda like a built in delete plate. If sonny wants to cut it for a din type radio, I dont care. I will do my best to convince him of using a hidden audio setup controlled by his phone, along with a hidden jack plug in maybe in the console, or in the ashtray. I figure the cigar lighter for 69 being in the ashtray, theres no need for a lighter in the dash face.
Another member did this very thing with the black and carbon look, and it gave me that idea. See pic # 3 of 72bluNblu dash. We will do the console plates like that too, and leave the buttons and knobs chrome. If later on my son wants to put repops in there or restore the originals, he can.
