Made my decision. I'm splicing the frame. Guess I'll be unsafe just like all the other streetrods with camaro, volare, and mustang II swaps.

Got a friend who has been building street rods since the 70's. He also said this will work fine. If I splice, and fish plate the frame it will be just as strong if not stronger than original in that area.

There are tons of med and heavy duty trucks on the road that have had their frames stretched and shortened this way. it makes no difference if I use 2 different year frames. These two trucks are old enough to have similar design and mild steel frames. The newer pickups are spliced from the factory with a very smal overlap and are plenty strong.

I appreciate all the help making my decision and I will post picks of the build when I start cutting.
Thanks.
