Na6 with 1.8 differential swap: driveshaft too short
 

Hi new here, hoping I can find a cheaper solution here quickly. In the process of installing a 97 1.8 open diff in the a Na6 but I realized the driveshaft is too short by around a quarter inch. The driveshaft I bought said 1.8 94-05 manual driveshaft. Though I've started to think they sent me an automatic since it was from eBay, because the research I found says the 1.8 95-05 automatic driveshafts changed by length through the years, but the info seemed like it wasnt very credible. So I'm hoping IF there's a cheaper route, like spacers?? Or maybe more info on fitment of the diff.

Oh, and on one of the diff mounts, the 2 smaller studs snapped. Are those a necessity? And are they a painful process to remove and replace?

Dont bother with making up spacers etc for the tailshaft.
You can buy them for $50 from a wrecker.


as for the studs, you're talking about the two smaller ones that hold the plate near the main diff bolts on the moustache bar?
If so, then yes, they're important.
They locate the other half of the diff bushings, and actually hold the diff in place.

Do you know how long I can drive it, without it breaking or wearing out other parts? I need to buy tools to pull the studs out.

You can probably limp the car around for a few ks without an issue. Just be easy on the throttle and dont go too fast.
Ideally i'd just get a mate to give me a lift, or take the bus.

it's all really just a guess though.
