Seat Belt Question?

I am using the belts out of the parts truck as they were clean and red to match the rest of the inside I also used from the parts truck/

Question is the belt seams to short.
I have the seat all the way back, I am tall.
The belt will clip in and is not tight on me but if I was bigger or had the seat forward the belt would not clip in.
I have it pulled out all the way, will not pull out more to just get it clipped in.
If someone was shorter like my wife I don't think the belt would be able to clip in.

I have not tried the passenger side but if the same and she wants to learn to drive stick I would not be able to wear the seat belt because she is short and need to move the seat all the way forward.

This cant be normal for the truck is it?
I will pull the other set out of the storage bin and see if they are longer but I don't see that happening , longer.
So what you say normal? How can it be made longer & safe?
Thanks

I'm sure that isn't normal.  I've had two 81's and neither had that problem.  In fact, my daughter drove Dad's truck and she is so short she has the seat way forward and was able to buckle up easily.

And looking at the part numbers for the seat belts I don't see any obvious issues.  So I'm at a loss unless your shoulder harness reel isn't working correctly and the belt isn't able to come fully out.

At worst case, I have my original red belts and can measure them for total length pulled out.

Thanks guys I have today off, slow at work, so after some running I need to do I will check if it is pulling out all the way and the other side if different.
I will also pull out the old belts to see how they are.

The seat belts in my truck have always seemed awfully short.  My uncle, who could be fairly described as a portly fellow, is unable to buckle up even with the seat almost all the way back.

Is your parts truck perhaps a 1980?  Maybe it was a one-year thing.

EDIT: I see from your sig that it's an '81...early '81?  Just speculating here.

Parts truck was 2/81 with red belts now in my truck.
My truck was 11/80 with dirty black belts.

I cant even reach the Ebrake re-lease it is so tight.
After my first cup of tea I will go out and check the belts out.

I have not pulled out the old dirty black belts to see if they are any longer as I have not had time.
I did check the passenger belt and it is just as short.

If the black belts are the same I may either need to find a set from a newer truck in the JY or add extension to what I have, only need like 6" to be good.

Thanks for the link, I did not start to look for them so that helps.
Now if it came in red that would be great!
Thanks again
