changeover no good on a 66

[sandfreek]

I tried changing the lower a-arms , no good the mounting is totally wrong on the 1/2 ton verses the 3/4 ton stuff..... Removed the crossmember and tried the 1/2 ton, no good.... The 1/2 ton is a inch narrower than the 3/4 ton between the rails.... I dont know what you guys are doing to make these things fit but I am pretty pissed about this whole thing.... Everyone is sayin it is so easy to change over but I sure havent had any luck... Ifigured it was a slam dunk but not so much...
