Steering Question: What u-Joints to use from GM Column to GM Box (78 Camaro)

[Maximus]

Hi guys,
I did some searching and couldn't come up with the info I'm looking for.
Here is my situation:
I have a 1978 firebird column in my truck, and the 1978 firebird subframe under my front fenders...
The steering shaft needs to be made up...

my first question is what dimension/shape u-joint do i need to mate the the late 70's GM column (is it 1"-48spline?)

my 2nd question is what u-joint i need to mate to the steering box (after I remove the rag-joint - chart appears to be 3/4"-30Spline?)

and my last question is -
what are people using for the rod to connect the two?
it appears that Speedway Motors have ujoints so you can buy 3/4" round shaft and weld...
but I was hoping to keep the "Crumple" joint in the shaft...
should i just extend my stock 1978 firebird steering shaft on one end and use the stock 'crumple' zone? or is there a longer shaft I could buy to replace the male half of the shaft and slip it inside the stock female half?

Any pictures and sized would me most helpfull!!!

I found this chart from Speedway Motors and wanted to make sure I was on the right track...

I tried to look things up in CPP's catelog.
(you might check their website)

You are saying:
Your steering column is: 1"-48 sppline.Part #CPP-UJ2)
Your steering box is: 3/4"-30 spline.(Part# CPP-UJ3)
You would just use "DD" style joints with a "double D" joint between the two.
The shaft material will be the 3/4-DD shaft. (Part# CPP1850-D)

Also look at their camaro steering kit part # 8050510
