From the drivers side photo, it looks like the Rangr head was mounted on a modified shotgun/radio rack which may be similar to the one used on the '92 EVOC. Here's a photo from the passenger side of that car after it was restored.

I can't vouch for the accuracy of that mounting. Try contacting the owners who participated in that project as they will likely have more details. The one who is on this forum is "xxtrpr." I found this photo on the Mecum auction site, you may be able to find more photos by searching the web.

Found more sale photos of the restored '92 interior:

I'm pretty sure that my dads was mounted differently without the gun rack, however the modified gun rack may be what the 92 originally had.

It had a bracket off the top of the dash connecting to the part of the radio rack where the gun rack would have connected (like in the 92).

Here is when we got it out and after I washed it and cleaned the interior.

Off topic: I spy a box bodied Caprice in the background - CHP?

It is actually a barn find 84 Oregon State Police Impala that my dad and his friend got to restore.

Original paint and interior, untouched for 20 years, still just like it left the auction(other than the hubcaps, whip antenna, and lightbar :) ).

Cool. And is that a 2002 B4C I see on the left? Don't mean to hijack the thread. PM me the details so we keep this on track. :)

No prob. PM sent :)

Sam, I won't be presumptuous and tell you or your dad what to do with his car, but if that were my car... :)

...I would consider only making a few changes to it. These cars are only original once, even if they are showing their age. I would clean the black X paint off the doors, and add the CHP logos and lettering back onto the doors and decklid (even if you had to repaint the doors white). Then you could look at adding the CHP equipment that it used to have, and call it done. That car as it sits is oozing with character!

I was thinking the same as you on this one, Bill.
