I have a set that are still on the '70 I'm parting out. I hope to have them off by the end of next week. I think they're the same size as what is on a '77...someone with more knowledge will chime in. $150 for all four. Mudship might help out with transporting.
Let me get them off first and then I'll see what I can find with mudship. The right front ubolts look like they've had a run in with a rock or something so I might have to use a gas wrench to get them off so I hope you wern't wanting the u-bolts.
I've never used anyone (mudship) before, but I'm sure they will want something for their troubles. Are you willing to pay whatever someone may want to haul them to you? I know there are several here who make the trip down that way frequently; we'll figure it out...can't be that hard.
If all else fails, I could meet you like in Tulare off of hwy 99.
