I can't find one for less than $800.

Do you have a 'relationship' with a GM Parts Dept or maybe a Service Dept employee? The dealers are supposed to maintain an inventory of tools. Some do, some don't, some have very accurate inventory, most don't. J-39046 is a multi piece special tool and if they inventory it, it's complete maybe you could arrange a rental or borrow. A dealer I buy from if I need a tool they have I can generally arrange it. If it's older they're inclined to, newer don't even ask! They've been very good in the past about lending various FSM for a project too.

The FSM has an illustration of the kit. There's threads related to DIY fabrication and I believe a '96 is maybe a bit different requirement.

Rent the one mentioned in the thread?

I don't know any service techs, but maybe I should look into making friends lol.

I found a decent looking one at harbor freight made by MADDOX that's looks like it's got what I need.

Thoughts on this kit?

For instance, my 40-200 in/lb Icon torque wrench is EXACTLY the same as the Snap-On one I have at work. Except the etching on the head of course, but in every other way it's the same wrench. As far as I can tell their Doyle, Quinn, and Icon brands are actually pretty top notch at a decent price. But I haven't really tried their Maddox yet.

I'm not a HF rep, but have had decent experiences with SOME of their products lines.

I could just rent one from the auto parts store, but $80 isn't terrible. Idk. If they have the same one at O'Reilly, I could keep it for cheaper. Maybe I should wait and see.
