1988 Monte Carlo SS 5.3l ls swap engine mounting

[Supersport88]

Sup gbody fam! What holes do I mount my engine clamshells too. I’m only able to mount the passenger side and the driver side won’t line up.
I set the mounts how the original ones were only three bolts are mounted to chassis. I have the hooker black heart engine mounting and clamshells

I only got three bolts to line up, drilled the fourth. There were some special instructions about how to line up the holes, so if you're using the rest of the Holley swap system, this is a pretty crucial part of the install.
