Core support dimensions

[vita]

For a 70 charger, Anyone have the opening measurements for a core support (lengths and heights) and dimension from corner to corner for the opening? I’ll need to see how big of pusher fans I can run. It’ll be a 26” opening.

I can have the measurements for you in a few days...say Wednesday.

The simple answer is:

18-1/4" opening height
22-3/8" opening width
28-1/2" opening diagonal​

Here's the rub: The width of the opening at the top and bottom is slightly smaller because the vertical sides have an inward joggle. So, it's a 22.0" opening width at the top and bottom. I can get you the heights of the slightly narrower opening, top and bottom, on Tuesday or Wednesday. See the pictures below for now. Let me know if you need any other measurements; and/or clarifications.

OPENING LOOKING FORWARD:
Note the offset opening width at the upper and lower corners. See corner pictures below.

DRIVER SIDE UPPER CORNER:
(The threaded hole is for mounting the radiator; bolt is removed)

PASSENGER SIDE UPPER CORNER:
(The threaded hole is for mounting the radiator; bolt is removed)

DRIVER SIDE LOWER CORNER:
(The bolt is for mounting the radiator)

PASSENGER SIDE LOWER CORNER:
(The bolt is for mounting the radiator)

OPENING HEIGHT: 18-1/4"
(checked near both sides & middle)

Also, my '70 Charger is an XP29N0G...it has the 383 magnum.

That is enough for me to work on. To clarify, would this be for a SB application being it’s only a 22” opening? I figured the BB would be 26” wide?

It's a mixed bag @vita. Take a look at Section 7, Cooling in the 1970 Charger Coronet Factory Service Manual.
