What's the condition of your transmission mount Anibal? It may need to be replaced. Check that all of your drivetrain mount points are solid i.e. transmission to engine, transmission to chassis, driveshaft carrier bearing mounts, driveshaft flange to diff bolts.

How did the pilot bearing look? The center support bearing would progressively get worse as you drove the car. I would suspect a mount, pilot bearing, or something loose in the rear suspension.

Also my 6 puck clutch shudders occasionally during engagement, but goes away once it's fully engaged.

Well what happened is that the clutch kit came with a different pilot bearing for the front wheel drive or mr's so it wont fit our rwd's I ran to autozone and they would have to order it and I was in a rush to get it done.. So used the same one but my dad .. (Which works with bearing All the time )said it was still in good shape .. So I
Put it back in. It's not a puck so it shouldn't do that. I know how the shudders sound cuz me and my bro just put one in his srt4 .. So it doesn't sound like that .. So I'll give them
A call and tell them I need one for my 86 they know about it.Bit will check everything before o drop it back down.. :(

And also it feels like That time that time when everyone ran from the hurricane here in Houston .. I drove my civic to San Antonino and after like 14 hours of traffic my civic started to shake I got it checked in SA and nothing it just went away .. And I drove that car like 30000 miles after with no problems... :? So that's why I ask

It's possible the throw out bearing may need to be replaced and or the flywheel may have very uneven wear. You didn't use the FWD throw out bearing that came with the clutch kit did you? That's a no-no. Ask me how I know ;). The proper throw out bearing is the original that was a bearing pressed onto a collar. The old bearing needs to be pressed off and a new one pressed onto the collar.

Is the car lowered to the point that your lower 2 4-links are either parallel with the ground or slightly angled up (chassis bolt point is lower than the bolt point on the rear end)? If so, this MAY explain your shuddering or it may be wheel hop that you're confusing for shuddering.

Also, the grinding may be due to loss of trans fluid through a bad rear seal or cracked casing or both? Have you changed your trans fluid? If not I recommend Pennzoil Syncromesh.

check the driveshaft carrier bearing for any play.
also if any bushes on the rear 4 links on the rear axle are worn it would give the same problem

Wheel hop with poor 4 link geometry. The lower pair of the 4 links (the longer set) should be set where the mount points on the rear end are lower. Re-introducing somewhat proper chassis weight on the rear end. This can be accomplished with either purchasing or making your own traction brackets.
