K-Frame ID

I am looking to pick up a V-8 K-Frame for my '65 Valiant. I found one but want to make sure it is in fact a V8 K-member. Do any of you have pictures or measurements of the two?

I checked the Schumacher sight and if their information is correct, the Slant six and V-8 K's are one in the same. Do any of you know if this is true?

The same guy has a set of V8 torsion bars. I would like to be sure that they are indeed V8 bars. Do any of you know what the part #s are for the early A V8 Bars?

Thanks in advance
Jason
