Changing pulleys on a Sanden 508 compressor

Not sure if this is the correct sub forum, but posted my swap questions here, so hope the moderators if a better forum.

I am installing a Sanden 508 AC compressor on my 5.3 swap. My bracket kit, specifies a 7-8 grove serpentine belt. The Sanden I have has a single V groove.

is there a YouTube video or pics, on how to change out the pulley/clutch ?

Here is the e Sandsen Compressor Service Guide that includes tools and instruction for a pulley removal.

I had a similar problem where I had 2 V belt grooves and needed to go to 6 serpentine grooves and Sanden only made 7 groove ones for my compressor.. I ended up machining the 2V belt to 6 serpentine.

Before:

After:

BTW, I noticed in the service guide something about that compressor was for R12. Not sure though.

is the 7-8 groove stuff for a supercharger?

Looks like I am heading down the same path. Where did you find the 7 grove pullies ?

if you had a 6 grove belt, & a 7 grove pulley, why could you choose 6 of the 7 groves that alighned with the serpentine belt ?

I put 4 tack welds to keep it in place.
