Seat Belt Extension

[judy2gene]

Hello,
My wife needs a seat belt extension as she can not
put the seat belt together with one hand. We had a
head-on with a drunk driver and one of the results
is that her thumb on her left hand does not bend.
We were told that all seat belt extensions were
matched and may or may not fit together ? What type
of seat/belt is it ? Can these be purchased ?
Thanks in advance. What a great place to get help !
