There are quite a few options, but if you already have a T5 with OD….I’m not certain you really need different gears to cruise at 60 mph. Do you know what ratio you have now and what OD ratio you have? Tire diameter would be good to know as well.
The truck is stock driveline now. The 235 and T5 are not installed yet. Need the rear end to (eventually) complete the conversion. T5 ratios's are: 1352-145
1985 - 86 S10
3.76
2.18
1.42
1.00
0.72
Edited to include tire OD is 29.02" according to Coker.
