1980 K10 SWB bed mount bolt hole spacing

[jdsegars]

I've had to replace a section of frame on my 1980 K10 and need to redrill the front most bed mounting bolt hole on both sides.
Can yall let me know what the center - center dimension is so I can drill the holes in the correct location while the bed is off? I don't yet have a replacement bed so can't use that as reference.
Thanks

Do you want an actual measurement from a frame, or is the bolt head spacing in the bed good enough?

I'd wait until I had my bed and use it as my pattern that way you aren't just a little bit off, making life harder.

@bucket thanks for the reply frame measurement would be nice! Thanks.
As @Ricko1966 mentioned waiting until I have the bed does make sense too.
Thanks all.
