[49chevy3100]

Was Up,
Not new to the Forum just been following threads doing research before I started my build now after a year I finally got the funds to build a 49 Chevy pickup 3100 was going start the build using the original frame but got a good deal on a 91 extended cab short bed s10 that I plan to use for frame swap. But after looking at the 49 3100 cab it seems like the ID plate is missing, now Im wondering should I try and get the ID plate with the original frame before I spend anymore money on it or should I do the frame swap and then try to register it?

Any help would be really appreciated this going to be my first classic truck build will post pictures of trucks when Im off work
