IT's stock non strut,I havn't priced A salveged unit yet and I don't have A core to exchange at the yard.If it's not to much more Ill wait till after the Holladay's and buy new,I was told I could also go with A Chevy S-10 Manual box insted of the rack-pinoin.I wan't to end up with one Deep Groove pulley on the crank to run my Altenator, and Im putting A Moroso drive on the water pump.
