Quick Question New to Manual Iroc

I bought an iroc that was converted from auto to manual and the speedometer cable isn't the same i think he said its electric and the old was manual so the speedometer isnt working. Is there something I can do to correct this?
Thank You for your help in advanced!

If it's cable-driven, purchase a gear housing and the correct gear(s) (if need be), put them in place, and screw the cable in.

The housing can be found below (after the home page opens, wait a second or two):

Sorry, but I am on the website and I have no idea of what I am to be looking for. I'm calling their customer support line for help now!

Re: Quick Question New to Manual Iroc

You need a "bullet", the little retainer piece, a screw (you can get that at the hardware store, it's a 6mm std thread thing), a drive gear (big round one), and a driven gear (long skinny). The exact gears you need will depend on your rear end ratio and tire size. Don't bother with "codes" for the ratio or with what's stamped on the sidewall for the tires. Instead, pop the rear cover and LOOK AT the gears (it's a GREAT time to change your fluid right now, anyway); and measure the tire from the exact center of the wheel to the ground with the car sitting on a level surface, and thetires warmed up with normal pressure.

From the above site:

#68XX. Chevy TH350 speedometer gear housing [the bullet that Sofa mentions), comes with both seals, no gear. (If you have an aluminum housing it needs to be replaced with this steel housing.) (Also fits T-5 and Super T-10.)
