Default Getting rid of the tri-flange?

So I picked up a CTSV T56 today, special ordered with the tri-flange setup. I would like to insall this tranny in my 1991 Silverado which doesn't have the tri flange setup. What is the best way to go about changing it/adapting it?

How it looks..


How I want it to be...


Any help is appreciated.

Search 1000hp t56 ssr ls1tech.com
And read the pdf in that thread.

If the shifter location is good for you, keeping it as-is might be a good option.

The shifter location is perfect, its exactly what I needed. But I'm not sure if I'm confused, or your confused but I need to figure out how to hook up to my driveshaft that I have now using the triple flange.

Whether someone knows where to purchase an adapter maybe even?

Driveshaftshop.com can make you a driveshaft that will work with the flange so that you don't have to convert the trans to a slip yoke. They do away with the U-Joint and slip yoke and use a CV that bolts up to the flange with an adapter. The CV allows the driveshaft to move in and out with rear axle travel. It will use a U-joint to connect to rear end.

A CV driveshaft won't have the travel that he will need in a truck.

This is what I ended up doing, its a 1330 U-Joint, anyone know how strong they are? Still need to measure out what driveshaft length I need.

I just wonder since it's fixed in place how well it'll hold up. Seems like there should be some give line a slip joint setup.

I haven't even started the swap yet so I couldn't tell you. The driveshaft will have some give in it when I get it made.

Make sure the yoke fits properly against the output shaft seal. I know a guy who burned up a perfectly good 5th ten Camaro unit trying to do the same thing as you are. He put a yoke on there that didn't fit the seal properly and it leaked all the oil out and burned it up.

Wow thanks for the warning, I would be beside myself if that happened. Alberta driveline is working with my so I'm trusting the "professionals" know what they're doing.

I was looking online for the same thing, unfortunately the guy who sold me the tr6060 was dumb enough to cut the centre support pin (it helps to align the aftermarket adapters). So, if u can help me with this, that would be really appreciated. im doing 2008 Mustang 5.3 turbo Ls swap with the tr6060 ofc, and yeah im from Alberta too (Calgary). I need to know what transmission did that yoke came off, and how is it holding up??
