Anything can fit anything is a very broad statement.... I fit a 8-71 blown dual feed nitros injected 70 vette lt block into a 80's S-10 with a nascar plate, Didn't make it right nor was it easy or practical.
The chassis design has to compliment the mount points of the suspension, as well meet the offset required for the body and rims/tires involved.
If you believe you can just take any chassis design part and throw it at a different chassis not designed for the job, I am very eager to see how it all works out on the first hard corner... I'm not doubting you but I am feeling you may be entertaining some issues down the road.
Chassis design is a very involved process and minor differences can be beneficial or catastrophic .
Unless you are using something like "inventor" software and stressing the final chassis design based on known factors I would be hesitant to just use a "looks about right" theory... Just my two cents, but I don't want to see anyone make an error that could be avoided.
