So I know that a 1990-92 speedo isnt a direct swap into an 82-89 thirdgen. Is that only because the 90 to 92 is eleteically driven vs cable driven or does it not bolt in at all either?

I want to change my 145mph cable driven speedo in my thirdgen camaro to a 90 to 92 eletrically driven speedo so that I can use a dakota digital box and a t56 trans with eletrical speedo output like I did in my 87gta which has the 140mph electrically driven speedo.

I realize that I need the pigtails and would need to run wires to the transmission speed output connector. I just need to know if it will bolt in or not. Dont want to buy a speedo if it wont bolt in.

 

Won't likely fit in the dash without serious reconstruction. You can make a custom one however. Do some searching for making an electronic cluster for the earlier years. Sure someone on here had done it with pics and details. Have fun!
