Will these 3.73's fit my 305 tbi

As long as your '88 TA has an 82-02 10-bolt rear, yeah.
You'll need to change the speedo gear on the vss (maybe the one in the trans. too) so you have correct speedo reading.

This is a 3.73 gear ratio, only works with a 10-bolt 7.5 (7 1/2") or 7.625 (7 5/8") 3-series carrier. This can be used with a 2-series carrier only if you install a ring gear spacer and longer ring gear bolts (not included). Most 93 and newer applications require PCM reprogramming if changing the gear ratio. Fits the following applications:
82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92 Camaro, RS, Z28, IROC-Z with a 10-bolt rear differential
82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92 Firebird, Formula, Trans Am, GTA with a 10-bolt rear differential
93, 94, 95, 96, 97, 98, 99, 00, 01, 02 Camaro, RS, Z28
93, 94, 95, 96, 97, 98, 99, 00, 01, 02 Firebird, Formula, Trans Am
82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92 Camaro, RS, Z28, IROC-Z with a 10-bolt rear differential
82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92 Firebird, Formula, Trans Am, GTA with a 10-bolt rear differential
93, 94, 95, 96, 97, 98, 99, 00, 01, 02 Camaro, RS, Z28
93, 94, 95, 96, 97, 98, 99, 00, 01, 02 Firebird, Formula, Trans Am
