JW, the speedway will be the best choice for the money. Sold by Speedway or by Amazon. Same price. You ALWAYS want to mount the fuse box upper left of left foot on inside of firewall, if at all possible.
There are cheaper kits, but in my opinion from unknown sellers and/or makers.
Don't get too wound up in wire specs, they are all suitable for our trucks. Crosslinked or PVC. Not sure what you meant by the need to de-pin and pin. Nothing is terminated (pinned) but the fuse box end in the kits. The YNZ type would be very difficult to modify and defeats the purpose.
No one knows what prices will do now-a-days so "bite the bullet" and "pull the trigger" if you are ready to wire. We are here to help. Wiring is best done when most other restoration/refurbish/preservation tasks are complete and all electrical components are in place.
