Front is standard swap: Use 71-87 front parts. 73-87's are easier to find in wrecking yards if you plan a budget approach vs. buying a kit from a vendor.

The rear is going to require swapping..... thus some searching for the replacement. If it's a rear coil truck, 71-72 5-lug housings are a direct swap. 67-70 6-lug housings are 1.5" narrower than 71-72 housings & can have aftermarket 5-lug axles/drums swapped in. 73-87 housings are wider like the 71-72's. These will require more effort for the swap depending again on rear suspension type.
