What speedometer gear do I use with a R154 and 4.30 LSD?

I'll be running an R154 with a 4.3 soon and am interested in this ratio adapter too.

I am already running a r154 with a 4.30 not from stock, from a swap and my speedo is 70mph at 60mph gps.

This is the reason why I want to find a speedo gear for the R154 compatible with the 4.30 gearing.

The speedo is off roughly by 10%
if you use a 4.10 R154 speedo gear drive for a 4.3 diff

So if you increase the diameter by 10% or get as close to it as possible using the jdm 4.1 r154 drive you should be really close.

I'll keep this in mind. Thanks

Any word, John?

Would installing an A340E driven gear onto the R154 work?

No.

As i said. 4.10 Gear FS.

Auto Turbo is 6:8
And NA Auto is 21:6

Anyone ever get a definitive answer on what to do for this? I too have an R154 with the 4.30 and want my speedo and odometer to work correctly.
