Polyurathane Leaf spring bushings question??

[amodedude1]

I was wanting to buy some leaf spring eye bushings from LMC truck, but their catalog is confusing the C@#$ out of me. Could someone help?!

I went to the shop and measured my leaf spring eye's. I measured the inner diameter of the leaf spring eye on the leaf spring. I could not measure the shackle eye as it is still installed on the truck at the moment.

My measurement of the I.D. of the leaf spring eye was an 1 1/2"

LMC catalog says "#### is for trucks with a 1 1/2" OUTER diameter diameter main eye bushing"

Do they really mean inner diameter??? Or are they talking about the outer diameter of the bushing it's self and not the eye?

Can any one tell me what part number is the one I really need for my 1979 k20?

If you have a better place to order these from, then by all means tell me where!
