replacement seat belts

[cigar-]

Maybe this has been put out there already and I missed it in my search on old threads. Have a 1971 C-10 with original seat lap belts. They are half torn and don't work well.

Has anyone purchased new replacement belts for their truck? Have they worked perfectly? Have you had to massage them a bit to work? Are the replacements the same fit, form and function? Are the lengths correct?

I ask all these question because I don't want to get product that requires lots of mods and stuff. Have looked in the LMC catalog and they don't say "exact" replacement for length or fit.

I appreciate all help. Am going to look at a set of original black belts after work but want to have a back up source.....
