gauge conversion hookup

[Danny Thomas]

Not sure im in the right thread, but trying to find out if i can use my stock mechanical gauges in an ls1 / 4l60e conversion. Or what is available to convert wiring. This is for an 81 TA

the speedo wont work without a stepper box for the cable they make them kinda high dollar. tach idk. rest should be able to work if you install proper senders on the ls1.
