700R4 to SM465 swap - Driveshaft Length

[Mike_J]

I'm going to pick up everything I need to swap out my puked 700R4/208 combo for an SM465/208 combo this weekend. The catch is the driveshafts are not in the truck and are mixed in with several other driveshafts. Can someone tell me what length shafts I'll need? It's a LWB truck, but if I can figure out either the front or the rear, I can measure the ones from my auto and figure what the oppisite shaft needs to be.

Thanks

Mike

Once you get it in the truck just measure from output to input..

Forgot to mention...I'm picking the combo/pedals/etc. up several hours away from home, so I need to know the length when I show up, otherwise I'll have to eat the cost of having my shafts cut by a shop when I get the new stuff installed.
