v1.4 mods for SH4

Hello everyone,
Searching through Google and Subsim, it seems to me that most of the SH4 mods are designed for the v1.5 patch.
I was wondering if any of you were using the v1.4 and successfully added mods.
I'm not looking for graphics enhancements but rather a better sim experience.
Although if no mods are available, I will remain addicted to my vanilla version with the radio and music add on I've got on.
Thanks in advance
