Frame swap questions

[Spray-Bomb]

Hey guys, I have a question about swapping frames

I have a 67 chevy that I Z'd the rear & cupped my LCAs
Thing is I just dont like how it turned out
I also have a bagged 89 & they are MUCH easier to make lay frame

I can get my hands on a 88-98 frame for basically free (complete minus rear axle)

I know that the 88-98 frames are about 11" wider because the fuel tanks are on the inside of the frame

But does anyone know if there is a difference in track width ?
Im not worried about wheel base differences, as its easy to shorten or lengthen a frame (to me anyway)

And I know all the body mounts have to be moved to the inside of the frame
My main concern is the track width as that is hard to change on the front

I would just measure the difference myself, but I dont have the front suspension on my 89

I know a guy that swapped his 67 on a 4x4 88-98 frame, but track width isnt such a concern on a 4x4

Thanks, Matt
