Leaf spring bushing HELP please!

I have a 1970 Dodge Dart custom sedan w/225 slant. I have been in the process of changing all the suspension this past week...the leaf spring bushing are holding me up. I've ordered them twice from different places and I keep getting the same size. The problem is the leaf spring eye on mine is 1.5" dia. and I keep getting 1.375" dia. and I know the V8 model has a 2" dia. Whats up with this? Any ideas why I have a 1.5" eye and what part number for the correct bushing.

I did some looking thru different vehicles and found that a 85 jeep cj7 has 1.5 dia bushings which I may try if nobody has any info.
