Plug change on big block w/AC - Tips? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm about to change plugs and wires on my 70 GMC 402 w/AC, and I'm sure others have been down this road before me... it looks OK except for the two on the front passenger side that are below the AC compressor.

Any tricks? Do I need to remove the compressor, or go at it from below, or just skin my knuckles and hope for the best?

Thanks,
Dave

You can get at them with the compressor in place. I didn't think they were too hard to change when my truck had a big block.
