Here ya go. A lot of people use the ZZP coupler with great results.

Do it yourself. Many of us have. Moving this topic to Forced Induction. Sol, you big ***, you should have moved it!

I'm just keepin ya on your toes Bill.


Actually, not really. I wasn't paying attention to where this was.

LOL


GM doesn't sell the couplers because they wanna screw everyone into a $2000 */C to fix a $36 dollar part.

Yep, replaced with zzr coupler on my 93. Cram a rag under the nosecone before you remove. An easy job!

First of all, GM also sells the nosedrive assembly by itself for about $700.

Secondly, cramming a rag under the snout of a 94 will accomplish nothing. The whole SC must be removed from the engine to get the ND off. 96+ Bonnevilles can remove the ND on the car, 92-95 cannot. But it'* still a fairly easy job.

Me and fantastic88 did my coupler and pulley in about 2 hours??? That was also with replacing a bunch of gaskets ans hard to get at with the */c on stuff too.

Hmmmm, my engine is from a 95 Riviera. I did take the nose cone off to replace coupler, though. Maybe the Riv engine is different?

same engine, same way my dad did it...purely preference...
