Stock vs. Modified Poll

[JesseB]

Recently purchased a '72 Custom Delux from a 68 year old man that owned it for 30 years as a second owner. Everything on the truck is well maintained and stock- even has original hubcaps. I am debating whether to modify certain items such as the A/C system to a Vintage Air 134 system (Sanden 508 compressor and brackets), which would perhaps perform better; however, it screws up the integrity of a classic. There's the rub.

How do you all vote??
