62 c10 front end swap to a 64 help please

[superpieboy]

Hi everyone
I will be trying to replace the front end of my 62 that has torsion bars to a 64 front end so I can put air bags on the front, Ihave not bought the 64 front end yet! what I need help with is what parts can I reuse fron the 62 front end that will work with the 64, example can I just purchase the upper and lower A arms , cross member , and the side engine motor mounts for my 261 L6 .... can I retain my stock 6 lug 62 spindle and hubs and will they bolt on the 64 A arms? the wrecking yard guy says that i will need the 64 spindles and that my 62 spindles will not bolt on and do I need the 64 steering components like tie rods and whatever else, Its just that the wrecking yuard wants to charge me for every single piece and not give me a total price for the whole unit.....

thanks
jeff
