Readily available 5 speed conversion kits?

1) which company has the cheapest 5 speed kit available? I’m only aware of keisler, but not sure if it’s complete with everything needed to do the swap. For a small block la car, originally a904.

2) For anyone that has purchased and installed one, did it have everything you needed to do the conversion? Or did you need other parts? Does anyone have a link

I did search but didn’t find exactly what I’m looking for
