I am still trying to dial this in. It looks like i will need adjustable upper control arms along with my lowers to get the pinion angle where it needs to be (the pinion angle is not currently +/-1 degree, which is my goal). With the additional castor built into the housing, i should be able to meet my goal of dialing in the pinion angle while maintaing factory castor, i'l let you know how it turns out... With the factory housing, i was set around 4 degrees of castor and the pinion angle was somewhere around 4-6 degrees...

sdhexpert- We're again considering an adjustable track bar mount. As I said earlier, it won't suit everyone but we hope it covers most applications.
mvbeggs-One of the weak spots of the stock Rubi frontend is the axle circ-clips. They don't like to stay in place and tend pop out causing the axle ears to become damaged. Many PR44 customers are using our conventional housing so they could use a 30 sp ARB (or any other conventional or non-rubi diff).
jmolfino-In our PR44 housing selection (http://dynatrac.com/images/pdf/Choos...using_revC.pdf) PDF it states 'The ProRock 44 Unlimited housing has 10 degrees of separation between the pinion and caster axises. This allows the end user to run between 6 and 8 degrees caster with a pinion angle between 2 and 4 degrees pointed up.' You should be able to get more caster and less pinion angle from your set up.
As for a drain plug, there isn't any area beside the ring gear to allow a plug. The plug would have to go right in front of the ring gear and would require a protruding bulge in the lowest portion of the cover. This bulge would be very vulnerable to rock damage.
