1988 F250 Frame Question
 

Hi Guys ...im .New To this forum and a 88 250 plow truck8ft bed reg cab .... but not a ford truck, owned a ford truck since 84, quick question to any one of u with extreme knowledge in 4x4 & 4x2 , just moved to Maine 2 yrs ago, so came across a nice 88 250 gas 5.8 Windsor 4x4 plow project. also found a nice 4x2 doner truck w 77k no rust, I'm pretty sure the2 frames on these are different, up front 4sure, but anywhere I can find the exact difference? I have both VINs . Thanks in advance Phil
