700R4/NP205 Length

[zac]

I've read through some of the threads on this combo, my question involves the overall length of this package. If I end up going this route, I will NOT use the spacer, I'll do the output shaft swap. I swapped the output shaft on a TH400 this winter. Had never done it before, used a book, was surprised how easy it was. Been afraid of pulling apart an automatic all these years for no reason. My '70 burb has the 465/205 combo. I know you need the 205 that was bolted to a th350 for spline match, the adapter also, right? How about the crossmember? And where do we end up on length? Shortening/lengthening driveshafts how much? I have another identical basket case donor truck so I have spare shafts, but at this point in my life I'm not a big fan of cutting and hacking when there's a more elegant solution. Thanks in advance.
