I had an upholstery shop shorten some for me. They used the same size thread and pattern with twice the sewn seams (did the same pattern twice) as the original so they should be just as strong as they were or better. When you cut the belt off take a lighter or small torch to melt the edge so it doesn't fray. Then fold it over the same as it was where it goes through the buckle.
You should be able to find a shop to do this for you in your area.
If you can’t find a shop to shorten them, try a shoe repair shop. They usually fix luggage, heavy duty zippers, all kinds of stuff. I had some car tie down straps fix at my shoe guy. I would imagine they could shorten your belts.
Just curious, what is the length of the belts you received? I thought i remember the correct length to be 74Ē. It is not impossible that the vendor for Danchuck to have mis packaged the belts. If this is the case, Danchuck will make it right.
I don’t have stock seats in my 57 Gasser so that’s probably why they are so long. But regardless they are too long and I’ll have to get them shortened. I had Black previously that fit great but wanted to switch to the brown to match my interior.

I ordered 74" seat belts for the front seats in my stock '55. I laid them out where I thought they should go. Put the seat as back as I could go, and I couldn't get them buckled. Too short?? I then ordered the next size bigger; 90 inchers. I didn't try them, but you have me thinking if the 90's are too long and maybe i didn't measure correctly for the 74's. Hmmm................, Carmine.
