Frankly with the hoses and such I would just buy new ones and save yourself the headache of having to replace them later if you go with used.

I'd investigate the 2008-2012 Colorados that had the LH8 & LH9 engines to see what may be common, or pretty close. I bet you'll find those parts off a Colorado quicker. The oil pan I *believe* is available as a GM Performance part. I don't have a part number handy. Maybe someone can chime in. If you keep the I-5 4L60e, there's something different from the Alpha 4L60e. Pilot bearing, or something, I can't remember the details. Another thing to investigate. I'm guessing you'll do a 6L80e anyway.

Thanks for the input, I have a list of all the part numbers already, just trying to save some money if anyone happens to have some used parts they aren't using.

I5 trans won't work. Bell housing and input shaft are different. A V8 Colorado would make a good donor, but they're not very common. I think the exhaust manifold is still available from GM.

Stonedan, where are you located? I noticed you're using a different email than the one with which you signed up.

I have a brand new, never used belt tensioner that does not fit on my Alpha (this part was replaced by a different unit from Magnuson when the super charger was installed).

You can have it for the cost of shipping, let me know

Ramrod, Thanks for the kind offer but my donor engine came with a complete front drive so I should be set there.
