´67 weekend driver

[chevyc10lover]

im almost ready to start the frame off in my 67.
ive had it for 6 years most of this time in storage..
the only thing i ve done is put a 5.7 vortec /4l60 is mounted but not wired.
i already have a painless wiring arness that i bought last year.

i bougth the engine, transmission, diff. tank. radiator from the 1999 donor truck.

plan is to use the new diff it has disc brakes, i hope i can narrow this since it is wider than the stock rear diff. any one has done this diff swap??
i will post pictures later.

i hope i can start next week.
