Speedomiter differance

I just bought a 93 SC and the odomiter just stopped turning. I am thinking about replacing it with a 140 94/95 style. The question is, will it still read the correct speed or will I need to do some spedo gear changes if so. I also wanted to know if anyone knows how much psi the 5% sc pully puts out? God bless.

93 SC 5spd

The speedo will work fine. The differences are all in the speedo gears in the tranny. I think a 95 with a 5% will see about 15-16psi.

Thanks you answered them both. God Bless.
