Yes, 4.30 is gone, and 4.10 is the next to go, if it hasn't stopped already .
It's really a shame that USLC bought the exclusive rights to these gear sets, then discontinue them.
A lot of drifters and pony stock guys use the 4.30, and so do I and some of my customers.
If they don't want to carry them anymore, fine, but then need to open the discontinued ratio's back up for the public to purchase.
Call Richmond and they will tell you that you have to buy it from USLC only, they have the exclusive rights to all the Toyota 6.7's, but USLC wont sell them to you.
