Tie rod q?

[KiltedBanshees93GT]

Synopsys:
I'm going to be doing the tie rods on my car soon [the 93gt] (was going to be this weekend, But...)
Correct me if I'm wrong, but this looks exactly like the manuals drawing for the inner tie rod, but they claim its a "rack and pinion socket"
part in question
Is this a case of "po ta toe, pota to?" or am I a dingbat?<g>

The reason I ask is that we've hit a bit of a snarl, since the part is $20, showed as $20 each at check out, but they charged me 39.95 each, for a part that is exactly the same, but with an "02" suffix.
According to them, ...this is an exact quote from their email....
"The 01 or 02 stand for the two different warehouses we ship out of. "

I'm waiting for a reply to the last message I sent them, basically a big WTF?. They said I could send them back, but I'm not going to pay shipping 3 times on these things.
Opinions?
