2" longer front driveshaft (NP205 to 10-bolt)?

[guido666]

Is there a stock shaft from another truck, tranny, etc. that is a couple inches longer then mine? I have a '79 Blazer with a SM465/NP205 and after my BDS 4" lift the front shaft is way too short. At full droop there is at least 2" u-joint to yoke gap with shaft fully extended! I don't have $300 for a new one, and calling around they say it would be that much to lengthen mine (another beef altogether). Any other suggestions? I just want 4WD for winter, I can buy fancy (expensive) parts next summer.

Anyone? Even a confident NO would tell me I'm screwed and have to come up with the $$$. Someone please help.

the sm465/np205 is the shortest front driveshaft GM used. you can probably find a th350/np205 or a th350 np203 driveshaft and it may be the right length.

or if you just need a quick fix try a driveshaft spacer that goes between your t-case and driveshaft. they sell them at 4wp i beleive. when i put my lift on at first the shaft didnt fit in there but sprayed some pb blaster and let it sit and it slid out just that little bit that i needed

Awesome! I'll look for those spacers, any idea how much?

Those other longer driveshafts mentioned, will they have the 4-bolt flange on the one end?

There is a good 2" gap when the axle is at full droop. I just now thought about it but it may be even more in off-camber situations if the driver's side wheel forces the passenger side (with the diff) down just a little more.

as long as you get them from a 76 (or 77) and newer truck it it has the 4 bolt flange

 

[guido666]

Will an '89 front shaft work too? (Just double checking).

 

[big83chevy4x4]

it will work, will have the 4 bolt flange, but its way too long. IIRC its like 6" longer than a sm465/np205 front shaft. it is cheaper to have them shortened than to lengthen them.
