This person is (was?) making 3800 mounts:
His email is: firstname.lastname@example.org but he no longer seems to reply to any emails.
Update 11-9-19: This may no longer exist. Do a search on the various Fiero sites. There is a Facebook group for 3800 Fieros. If anyone finds someone that is now making any 3800 mounts please let me know and I'll update this page
I do not sell them. I am only posting this for reference.
