Projects How much trouble am I looking for

I am looking to built a 1938 Olds street rod and want to know how difficult would it be to swap the olds body to a late model chassic. Any suggestions what chassic to use.

 

Too difficult to be worth the trouble. Nothing fits, you would be better off upgrading the Olds chassis.

 

im building a 41 olds and seldom scene is right nothing fits i did update the chasis with a chevy pick up rear end it was the only one wide enough and did a scare bird disc conversion on the front
