found 700R4, need some opinions

[likaroc13]

hey guys,

I have a 66 short/fleet with 327/Powerglide combo. I'm looking to eventually switch to a 700R4. I came across this one last night on Craigslist, but i have no idea if it's a good deal. What would you suggest for the torque converter? my truck is basically stock, & i'm just looking to make a nice cruiser (in-town/highway)...

and from reading, i understand the driveshaft would need to be shortened...where would i look to have that done?

also, do you think i'd have any problems getting rid of my Powerglide if I switch to the 700R4?

here's the ad:

thanks for any info/opinions
