Are the Revell 1/25 69 Camaro & 1/12 Camaro Directly Proportioned?

Does anyone know with certainty if the 2 kits have the same proportions? I want to download a bunch of 1/12 scale files and scale them down to 1/25, but I wasn't sure if the hood and other tight fitting pieces would have the proper proportions.

I would tend to doubt that they would be, because the Revell kit was new tooling, upon its release. I believe the 1/12 kit is the old Monogram kit. At the same time, the Revell kit was released after the Revell-Monogram merger, so I suppose there's at least a chance they based the 1/25 kit off the 1/12 one.

if your printing it yourself you can usually resize in your slicer. just measure the size of the part you are replacing and transfer them to the new part. if they are scaled correctly they should fit and if not you can adjust the next print. your biggest issue might be the profile shape as thats where any discrepancies will show up most but adding some depth to it can give you extra materiel to  reshape with files and sandpaper

Get one of each, and measure the key areas.  I'd bet that Monogram still had information gathered for the 1/12 scale kit in the archives at the time they were acquired, and Revell used it in the creation of their kit.  Both of them look "right".

My thoughts as well.  If you are scaling them yourself, scale them to the exact size you want vs. just scaling them to a % of a %.

The exact size isn't an issue, I do a lot of fine tuning on the sizing and %, it's the angles I was worried about. I don't know how to use the other software to change the actual files.
