LS1 Passenger side head mount accessory spacer for LS1?

[yzguyfl]

I have a supercharger kit for an LS1 a corvette (obviously made for the corvette pulley spacing) that I want to mount on my Fbody LS1 with Fbody accessories (spaced out ¾” further from the motor than the corvette). The supercharger mounts to the front of the passenger side head (3 bolts).

Does anyone make a ¾” aluminum spacer to allow bolting up corvette accessories to the Fbody belt spacing? (kinda like the water pump spacers, just for the passenger side head)

I have just put the bolts through a stack of washers that measure ¾” for mocking things up, but will have a better spacer before it runs. I can make one if I have to, but if I can just buy one, I would probably just do that.

Holley makes spacers in different thicknesses for their brackets. You can check them out here https://www.holley.com/products/ls_power/accessory_drives/ Here is a picture of the spacer for their A/C bracket that bolts to the passenger head that I used.

I tried calling them to see if they had something, and was told they did not have a 3/4" spacer for the passenger side head, they just wanted to sell me a kit for everything, which I don't need. I can't tell where that part would go, or how thick it is. I'm making one out of 3/4" by 1" aluminum bar.

^^ above bracket is only about 1/4" thick. You can buy it separately from Jegs or Summit for about $50

I tried calling Holley, and the person I talked to really only knew about the whole LS1 accessory drive kits, and did not think they had anything like what I needed (really not sure, as they did not seem particularly knowledgeable about LS accessory drive stuff). I ended up going to emachineshop.com designing a spacer, having it made, and using that.
