Hi group. I looked through the archive and could not find what I needed so hopefully someone can help. I need the speedometer housing for my 4+1. I have nothing but a transmission so I need everything including the gear and any hardware to attach it. Any help is appreciated.
Thanks,
John Weaver

John,
Try calling Richmond gear. They list all the parts in thier catalog, I am sure they would be glad to sell them to you :)

Doug Nash used all the speedo gears and housing from the Borg-Warner ST-10...
The housing the driven gear rides in is the same as a Muncie...
Doug Nash sold the 4+1 to Richmond... Hope this helps... Crash

I looked on the Richmond page and they show the gear only. If this stuff works out of the gm lineup, where is the best place for me to get it. Like I said, I have none of it so I need everything.
Thanks,
John Weaver

John,
I have all the parts you need. If you give me your tire diameter and rear-end ratio I can compute the drive and driven gear needed to make your speedometer read correctly...Crash

Are you needing the TAIL HOUSING, or just the fitting for the plastic speedo gear? If you need just the fitting for the speedo gear and the plastic speedo gear plus the gear that goes on tail shaft, those should be too easy to locate.

Thanks for all the replys everyone. I guess my next question is which gear do I want? My speedometer is electric and can be adjusted but for what it is worth the tire diameter is 28". It will be nice to be able to go to the dealership and actually be able to buy something for this car.
Thanks again,
John Weaver
