Thanks for your cooperation and endless support Shawn.
Ok here is what I have come up with, excuse me if this is redundant but I just want it to be sorted.
So it appears only a handful sell the caster bushings.
The three retailers I have found (with help from squirlz and Mike) are:
JGY:
(Part #: KCA303) (70 rate compound)
JGY:
http://www.jgycustoms.com/serg20/suspension.htm
@ $49.25 (Pair+ship)
Tien, The current distributor for Superpro (Whiteline) bushings:
(Part #: SPF1340K) (80 (+- 3) rate compound)
http://www.tein.com/products/superpro_price_05.html
@ $58.00 (Pair+ship)
Global Performance Products:
(Part#: KCA303M) (90 rate compound)
http://www.globalperformanceparts.com/sentra-c-399_794_839.html
@ $83.21 (Pair+ship)
I have yet to find more (will update if I do!).
Now the other thing that has clearly been nagging me is: Are either of these the "Race" edition of the busings. Apparently the bushings came in three compounds (70,80,90):

Seriously, I think every tuned SE-R Street or otherwise needs some of these.

(sometimes lots of caster is not good for autrocross for complex reasons, but its usualy way past the 3.5-4 degrees you get with these) The new part number is KCA303M. The old KCA303 is 70 durometer and so is the SPP.

Ok so there we have it. All three types and the prices seem to coincide with the compound
, not happy about the price of the "RACE" bushings, wonder if it is really worth it (Mike suggests it so..)
One last note, Mike did mention that they do not list the race bushings on the website. Superpro has a lot of listings on their online catalog:

Here is a screenshot of the page for the Sentra bushings:
As you can see they have a few different variants of the bushing including:
SPF1339K : 1 x Offset 1 x Standard bushing, to adjust caster settings
SPF1340AK: 2 x Offset bushings, Increase positive caster both sides
SPF1340K : 2 x Offset bushings, PS increased DS decrease caster
Difference between the last two?? Maybe you can see what I don't Shawn..?
Let me know if anything is missing. I really don't want to drop $90 on these bushings but its looking I might have to.
