4sp to TH350 procedure

[xtinc]

I have a '67 C10 Fleetside LWB. I'm getting ready to replace my 4sp manual transmission with a TH350. I'm looking for someone who has accomplished this task that could give me a little insight on what's involved. Couple questions I have are:

1. Will I need to cut a hole in the floor of the cab to reposition the shifter or can I use the existing hole? I have not decided on type of shifter I will use yet, maybe a Lokar. Any suggestions.

2. Will my existing drive shaft work?

Any other tips will be appreciated. What happen to the search function anyway?

Thanks
Tom
