Im in the process of putting together a truck, "Frankenstein" is the name it acquired.. lol. Anyhow the rolling chassis I got was from a fire co water truck. No body with the chassis unfortunately. But I also noticed that there were no shocks on the rear, nor a crossmember or frame mount to mount then to?? The brackets are still on the differential housing tho. My question is, Whats supposed to be there? Or is this common?
