Bastard u-joint part #?

carpeonnel · Dec 21, 2007

bout to have my 89 rolling again but the bastard u-joint I got for the 14bff I have swapped in, isn't the right size :mad:

. Anybody got a part number from a previous experience? You'd make my life alot easier

Did you keep the stock drive shaft that turned the 12 bolt?

JPMSK5 · Dec 21, 2007

Yep, got to know the driveshaft, I run a combination joint from a 12bolt driveshaft to the 14bff. 348 Napa 1310 to a 1350 Dana Spicer

I bought a Neapco 2-1153 (of course I haven't bolted it up yet)

Napa 447 was what I used in both my 89 and 90 when I swapped to the 14ff.

I have an '89 K5 with the stock driveshaft and a 14B FF rear, with a PN 447 Napa joint. It is my daily driver.

My friend at Napa sais the 447 is now the 2400447. Hope that helps..

Napa changed there numbers by adding numbers to it to call them thier own. But the joints still come in the yellow box with blue lettering.
