I'm using the HD automatic that came with my 1997 Riviera 3800SC. I already put in the driver side axle, (original fiero axle).
I Bought a new Drivers side STICK Axle for the passenger side. Exactly Which CUP do I need to make this work ?? ( seems it has to be the" large spline" shaft going in, and a Cup for the "small rollers") What is it, and "Where" can I get one ? Thanks

I assume you have the 4t65e-hd trans and not the 4t65e or 4t60... I believe you want the 4t65e-hd passenger cup, the 4t65e-hd drivers axle and a manual fiero outer cup. Of course variation is based on where the engine/trans is mounted (which venxor mounts).

Isn't it strange that after a bombing, everyone blames the bomber, his upbringing, his environment, his culture, his mental state but … after a shooting, the problem is the gun?

The 4t65e-hd Stock" Cup" takes the Large Tripod (I have a stock one, the shaft is right but the cup is too large ), the Fiero Stick "Tripod " is the small one. I need a CUP that has the large input shaft and the cup for the small tripod. I've seen it mentioned as a cup from a "W" body. (What is a "W" body ?)

Will the tripot assembly from the Riviera swap onto the Fiero stick shaft?? Then also use the larger Riviera cup?

Tripod from the Riviera is too big for the fiero shaft. the stick fiero shaft is bigger than the automatic fiero shaft, but smaller than the Riviera.

the Riviera axle is also too long to use.

wbody are grandprixs regals impalas monte carlos and intrigues

The size difference between the HD tripot and the "Stick axle" is .07" ,tripot hole being bigger. So, the GTP "Cup", has the HD "axle size", and the Fiero stick "Tripot size" ? I Just want to be sure of this Before I go buy one. Thanks

I believe that the only two axles/cups that work are the Grand Prix and the Regal.

Thanks, Now to find one !
