I have a 1978 Dodoge Little Red Express Truck that I am converting to a 4X4

I purchased a 1977 Dodge W100 short bed as a donor truck and it had 6" high lift blocks under the rear suspension that I ASSUMED were after market. As we were doing the body swap I removed these blocks and now have found that the rear of the truck sits 6" lower than the front of the truck. It APPEARS that the front suspension of this donor chassis is stock suspension.

I am about ready to reinstall these lift blocks but wanted to see if anyone knew anything about this situation and if indeed these are factory items. If not I guess I need to know what could possibly be the problem here.

Thanks in advance.

 

Didn't realize they were 6",but yeah the factory sleazed out and used blocks with regular 1/2 ton pickup springs and hangers. You can rework the front hanger by flipping it and sliding it down the frame and weld some gussets to it,flip the rear hanger and put the shackle under the hanger to do away with 'em. Gonna do my Ramcharger first chance I get.
Blocks suck.

 

That answers my question about my truck. I just assumed that it was to make up for the added weight of the flatbed.
