Any other hydraulic throwout bearings other than the junk McLeod 1400-22 for an lt1 t56?

I have the McLeod bearing in my car since I put it together 4.5 years ago. This marks the 3rd failure in under 10k miles. Sadly, this seemed to be the only real option for the olds to an lt1 t56 that does not include swapping everything to an ls style trans, shifting the trans back 2" with everything else that will require...
I have a standard push style clutch and the 1400-22 bearing and before I go an install #4, has anyone figured out another bearing to use?
It isn't an over extension issue, they all seem to work for a while, probably about 2 years from this one, then after sitting a few weeks the o ring failed and I have no pedal.

Thanks!

Tuned in to this one, interested to see the responses for when I need to buy one for my 455/T56 combo too.

I've got a Ram Clutches throwout in my '55 Bel Air with a T56 Magnum. It's been perfect for the 6 years and 14K miles that I've been using it.

I'm going to go back to the hydralic throw out and I think I'm going to go with the RAM. I had the Howe before and that let go and cost me a new performance disk so I have been using the slave cylinder and fork since then. We used the Howe in our stock car class circle track and that never failed but the car was only beat on for about 100 laps a weekend.

I plan to make some phone calls tomorrow to research this better, but the issue is the lt1 style t56 and how short the distance is between the pressure plate and the front of the trans.

Howe and ram were the 2 I was thinking of.

LT1 style T56 didn't come with a Hydraulic throw out bearing from the factory.

Did you have the imput shaft machined?

If not that is your problem

The weir unit does not require machining.

I've got a howe t5 setup on mine and i built a bushing to make up the .18" difference in the OD of the trans sleeve vs the ID of the TOB.

Probably had 5k miles on and it seems fine, but there are reports of them not being that reliable.
