Pardon the naivety here. Building a truck. I definitely have a 75 highboy frame based on the vin stamped into the frame, F26 and all the tells, width, front cross member, etc.
My question is: Are the rear cab mounts welded, bolted or both? I just picked this frame up, and on my frame they’re welded on. However they each have 4 holes that perfectly match up to frame, but no bolts were included with the frame. Frame is a west coast dweller with very little rust. But I guess they could have been replaced prior? A picture of an unmolested OEM version would be super cool if anyone has one. Ty!
They are riveted to the frame. Whether you have a set that is from something else is hard to say. Without them being mounted in the factory holes on the frame your relying on the PO (previous owner)'s skill set on whether to grind the weld and remove the bracket and then remount it by bolting it backup in factory holes. Here's a link documenting the brackets on a "Highboy".

I totally spaced them being riveted. Looks like previous owner got them in the right spot. Gross welds however. I’ll run some grade 8 bolts through them and call it done. Thank you for the info!
