Pulley's and belts

without the A/C, it'd be identical to the one on my '74 D100. If you'd like, I will get you the measurement of the saginaw pump pulley and the belt part # Im using so you can run a saginaw pump for now. I dunno where you want your A/C compressor to be, but I have a water pump puller for top mount A/C if you use a dual groove alternator. But if you want, I have a 3 groove crank pulley that will definitely come in handy for when you go A/C
