Front Leaf Spring Bushing Outside Diameter

[Davtona]

On the front leaf spring bushings on a 1969 b body what diameter are the bushings? Are there two different sizes? 69 parts book in section 17-17-3 shows two part numbers. It lists #1948869 as being for all except 426 & 440. It also lists #2403245 as being for 426 & 440. I have a pair of NOS 1948869 bushings and they measure 2" OD and the NOS #2403245 set I just purchased are 1.5" OD. Bolt hole in the center of the bushings is the same diameter on both part numbers. My question is do the 440 & Hemi springs have a smaller hole in the front of the leaf spring for the smaller bushing? This kind of makes sense to me as there is less rubber in the bushing which would tend to restrict the leaf springs movement a little more. I don't have a spring out of a car right now to look at. Wondering if anybody has been down this road before??

Been there done that a long while back.   Caltrac was nice enuf to send me the 1.5 aluminum bushings after they originally sent me the 2's.

Mancini sells 1.5 aluminum bushings separately.    http://chucker54.stores.yahoo.net/solleafsprin.html

HD springs have the smaller bushing. On the OE ones anyway. Order an aftermarket and there is no telling. Pretty sure the HD springs I got from Springs and Things had large bushings. Been a while though.
