--------------------------------------------------------------------------------

can anyone tell me the measurement backing plate to backing plate plus leaf spring center bolt to center bolt?

[watkins boyz]

no one??????

[WuchaGot]

I don't know.

i think backing plate to backing plate is 56".

center of spring pad to center of spring pad is 43"

Why do you need to know?

[watkins boyz]

i want to swap my 64 1 ton rear to a 1/2 ton 5 lug

[C-10 simplex]

Oh. In that case i think you're going to have to install new spring pads in which case you could just copy your 64's positions.

But i'm not 100% sure---it may bolt in.

[C-10 simplex]

Do you already have the 1/2 ton rear axle?

[watkins boyz]

no but i think its 3 inchs wider

[C-10 simplex]

How many lugs you got now?

[watkins boyz]

its a 8 lug 1 ton dana

[C-10 simplex]

So, are you doing this for more wheel choices?

My 73 and 74 1/2 tons are 64" from outside drum to outside drum. Ive got a 72 5 lug coil spring rear thats the same. The 6 lug rears are narrower by 1 1/2". 1 ton rears are always wider.
