Dirty Dingo LS Low Mount A/C Bracket

[Slowguy]

Not to raise up an old thread, but I didn't see any resolution to this really. I need to keep my compressor in the stock location because I plan to have a passenger side log manifold style single turbo above. It seems the options appear to be:

1: keep the stock compressor with stock bracket and modify the frame to deal with refrigerant lines and compressor clearances. This will not allow the use of sliding engine mount brackets.

2: Dirty dingo bracket with small sanden compressor. This seems to be the best fitting option as the compressor is compact and very tight to the block. I have POL tubular perches and was going to buy a sliding "adjust2fit" bracket to go with the POL poly mounts I already have.

3: Alan grove bracket which will work, but uses a larger sanden compressor. Might be a tighter fit? May or may not work with adjustable engine mounts?

With the LQ4 LS gen3 truck engine, is it necessary that I need adjustable "sliding" engine brackets? I won't know this (unless someone chimes in) until I actually fit the engine in place.

It would be nice to get what I need so I don't have to mess around with dry fitting the cab just to see if the block will clear the firewall etc. It is so much nicer to mount all the brake lines, fuel lines, air ride lines, wiring, etc, without the cab in place. I'll take more time and it'll be a much prettier result without the cab set in place.
