With the correct vss and 15 tooth grey drive gear yes.

Re: Nos 3.42 90-92 speedometer driven gear
I'm installing a 3.42 rear gear into my 92 Z28. What besides this gear do I need to make my speedo read correctly? It's a t5 if that makes any difference.

Re: Nos 3.42 90-92 speedometer driven gear
Thank you sir for your help. Will I just need the grey gear or do I need a different vss also?

I’m not sure if you need a different vss, looks like the gears listed on the link are cable drive. I would call them and ask
