Do 2nd gen wheels fit 1st gen?

To add to this thread 10 years later, I just put some 16” wheels off a 2020 TRD pro on my 2002 TRD. They fit great but you will need a spacer. For my wheels (5 spoke style ugly af) the 1.25” wheel spacer from 4 wheel p fit inside the center of the stock rim almost perfectly, but like stated above you could get away with a 1”. I found the 1.25” easier to source these days though. I figure the spacers will not do much wear on the ball joints, etc. because they match the stock wheel for the most part. I could be wrong though.
