I’m gonna assume it’s a Frankenstein like my other 3/4 ton. But look like you got the same info I did from the vin. 81 c10. It’s got one ton axles but what’s something I can do to verify what the frame is. The frame was all I really bought the truck for lol. The goodwrench 350, manual trans, np205 tcase we’re just bonuses lol. I got the title coming today along with other information from previous owner. Guy owned an excavation business and this was his tow rig. He pulled backhoes and other equipment until it started running rich and he bought an F550 to replace it. All in all I just hope it’s not a half ton frame especially for all the towing it’s done. I did measure and the frame is 6-1:4” tall and about 2-1/4” wide I didn’t measure thickness I didn’t think about it. I’m assuming it’s a D44 front axle since I cleaned the numbers up.
its also a 2wd to 4wd conversion unless he put a 2wd cab on a 4wd and changed the tunnel
tHE vin was c10 but your frame could be half ton or 3/4 ton . if its 6cp its heavier duty 3/4

if bex is right about that
@Bextreme04 it would mean knowing your year is important to know if your frame is standard cut or if its stronger. Like a C6p from 1981 , based on that, would be like what you want, but a 1980 normal half ton/3 quarter would be fine too. but a 1981 half ton frame would be less than ideal
Tell us those frame horns ,youll find a lot

The front crossmember being solid vs having holes also tells a lot (the rounded frame horns you can look at your other 70s trucks vs your 87 to see what i mean
