1990 Burb destruction for a 72 build

[justtime520]

So I bought a 1990 4x4 350tbi burb for a good price. I have plans to swap the tbi to my 72 3/4 ton truck. The burb is in exellent condition and every thing works likes like it should. I drove it two hours from pheonix to tucson with no problems except it got better mpg than my 71. I plan on robbing the wiring for the hole thing.
So my question is, What else can i take from it before i part it out. Thanks for the help
