Off hand I do not now how long the transmissions and transfercase are. I do know though.. that the Output Shaft comming off of the transmission has to be cut, inrder for the 2 to cometogeather with out breaking anything.
As far as having a transmission built.. It doesent matter which you use, after its built, the 47re and 48re are just as strong. It will depend on which one will be easyer to find for your core.
Portel-Tek will be producing thier own castings.. Thats what I am waiting on. They said the castings they recieved a few weeks ago had some flaws in them.. so they are going to have them recased by someone else. At the cost of an additional 8 weeks, give or take. But when all is said and done.. they say that these axles should be the replacement for the hard to find mog and volvo axles, with the avi. of a better gear selection, and parts.
As of yet.. I am unsure how long the drive shaft will have to be. Im waiting on the axles to come in before weld in the engine mounts and set the engine. .. so alot is riding on the axles getting done and in my rig. then Ill beable to take it over and have some custom axles made for the front and rear. Ill let you know what size they are when all is said and done.
About the 30d, I have found it for 1300, with a lense. not too much more than the 20d. And if I were to buy form one of thoes places on the internet.. I have found where you can buy a whole kit for under 1500, inclufddes 2-3 lenses case cover, etc. It just seems as if the prioce is too good to be true.. For now though.. Ill just use the camera which is built into our camcorder. This way ill beable to take a vid. of her when she first fires up.
