Whats compatible with a 69 C60?

[Det57]

Hi Gang

Recently purchased a 69 C60 wrecker and I am in the process of making up the "needed parts list". It has a non original - worked Chevy 350 engine 4 speed.

My questions for now are these:

What Glove box inserts fit? Exclusive to C-60's or other models?
Rubber cab floor mat? " " " "
Outside door handles? " " " "
Heater resistor?
Front fender side marker lights? " " " "

What is the best place to get these type of parts?

How about a new wiring harness for under dash? Ron Francis Wiring or does someone have another they had great luck with?

Thanks in advance for any info!

Thanks for your time. Looking forward to working on this thing.
