There are currently no listings for the front shocks for the 85 Chevette. The builder probably found a number that was close or was necessary to fit the build.
I can’t get the link to post, so just Google “Monroe shock size chart“. The mounting styles are at the end of the chart. Pick the mounts and then find the size you need, compressed and extended.
Good luck.
