look at mopar parts giant. it appears that there are 2 different setups. i just went thru this when i shortened an 86 long bed frame to a short bed frame. i thought that i had all the right stuff but things did not work out correctly. i went to two different pick/pull yards and found 3 trucks to pull the stuff off of. 2 were different. i still try to collect the stuff as i have a bunch of trucks. look at the p/p's.
