New to the site, pics of my 84 GMC Truck

Yes the front wheels will be 20" too. I'm planning on Budnik wheels they make a really nice product and they will custom make the backspacing for whatever you need. I have not decided on a specific rim just yet, the one above is a mickey thompson rim but they don't offer it in a 20" front rim only 18" and I don't personally think it is big enough. This F150 was in the 2006 SEMA booth and it has the 18" in the front and 20" in the rear. Not my favorite look, the front rim size actually looked worse in person than in this picture.
