Should I go with the a833 conversion?

Go for it, but do your home work first my friend! Unless you have a pile of parts to start with there's no such thing as a "cheap" 4-speed swap. You'll need floor hump, clutch kit flywheel (uless doner had that too with the transmission) all linkages for a body & bellhousing possible drive shaft length change. Possible transmission yoke. I know im forgetting a few pieces but those are the bigger ones that cost the most. I say go for it just know before hand what you need & what it will apx cost you.
