Driveshaft question

[88trailblazer]

This might be a stupid idea, but what the hell.

I have a 78 K10 with the th350, 203, d44 combo. The truck has a 6in suspension lift + 3 more under the body.

Would the front driveshaft from an 87-89 k5 fit if it has a 700r4, 205, 10-bolt combo.

I know the 700r4 is longer than the TH350, which means the driveshaft should be longer. But would it be long enough for the extra lift?

That may work well for yah...
Measure the distance from the flange to the center of the yoke.
Measure the length of the shaft...compressed/expanded.
Post some measurements...we'll tell yah if it will work.

I'll have to get those measurements. Or even better, I'll pull the driveshaft off my brother's 88k5 and test it out on my pickup. Once I have it on there, what should i look for? Should I try to flex the suspension or is that a bad idea? What's could go wrong with this if it's the wrong size?

You could compare measurements first...
