Here's the deal, there is a sweet 1966 1100A 4X4 for sale locally. No data plate, but the seller has a clear title that at least matches the truck's year. My 1954 R-130 has the serial number stamped on the frame, driver's side, between the front spring shackles. The 1100A frame is clean, clear, and not a mark on it anywhere I can see on the drivers side frame. The passenger side frame member has a 4 digit stamp up near where the bumper attaches, but that's all I can find. Those four digits don't match anything on the title. The frame seems to be original, because the 304, tranny, and transfer case are all mounted in what appears to be a factory install. No goofy fabbed mounts, it all looks right. The axles may not be original though, the hubs aren't big-six, and the front locking hubs aren't IH. I've run a title check with the Texas DMV, and the serial number on the title is still registered with the current seller. So if the data plate was grabbed by someone to register another stolen vehicle, they obviously didn't register it in Texas. I've applied for a LST with Super Scout Specialists. It's my understanding from other posts here on BP that with the title and the LST, I can order a new data plate sticker from any light line dealer. Is there anything I'm missing here? Does anyone know where the serial number is on the 1966 frames?
