Welcome Niemand
I had access to three new 63's when I was a teen, so I have a soft spot. You may know that that year only had it'sown grill
and the hub caps were only used for 61,2 & 3.
Leo is correct about only three six's The K series 4x4 got the old Stovebolt engine but the C series 2x4 got the new 230 or the 292. The 250 replaced the 230 in about 66. A 283 V-8 was also available.
We get to Spokane every year or so and vehicles survive well in central Wa. Have fun with your new truck.
