Any advantage in using 73-87 front crossmember?
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. Last edited by D-n-Tyke; Yesterday at 09:04 PM. |

I think in 72 the C20 would have had 8 lugs so wondering what you have. Perhaps 4 wheel drive 1/2 ton?

Sorry, both 1972 C20 I am building, and the 1974 donor suspension are off 2wd trucks.
And you are correct. The 1972 C20 is 8 lug, I keep mistakenly put 6-lug. |

You will get differing opinions but I have always swapped the complete x-member. The one deciding factor for me is that all of the ones I have swapped into did not have engines in them. .

Have you considered doing the caster mod while your doing the work?
