Body swap
 

Hey everyone. Does anyone know if an 89 K5 will bolt on to a 73 K5 chassis without any mods? Long story... Thanks for the info!

No it will not. The body mount locations are different. The floor in the 89 under the front seats extends back much further than the '73 frame can contend with. You would either have to put a rather large body lift onto it or rearrange the floor.

*Moving to Fullsize Tech* - Unless you were going to detail this process and were not just asking the question...
