Any advantage in using 73-87 front crossmember?

[D-n-Tyke]

Planning on swapping the front suspension on a 1972 C20 8-lug truck to suspension off a 1974 C10 5-lug truck. I have the complete suspension crossmember and all off the 74 C10. I just don't know if there is really any advantages in swapping out the crossmembers when doing this seap. The only thing I have found is the low a-arm shaft retainer u-bolts are bigger on the 74 crossmember. But is there anything else? Are the larger retainer u-bolts really that much better when the truck is just going to be a daily driver?

Would I be smarter to just swap over the 74 suspension components onto the 72 crossmember. Or it really is smarter to swap over everthing, crossmember included. Looking all the advice I can get on this. Thanks.
