Hi Guys, I have a 69 Camaro with a 4 speed and can't figure out what to do for a t/o bearing. I have the stock short ( seemingly only one available ) one made by Hays ( same makers of the diaphram clutch I have in it ), and I can't seem to get enough clutch release. If I want ANY freeplay in the pedal, I cannot get enough release.. Does anyone make an old style long bearing that will hold up to the abuse? I see that McLeod makes and adjustable, but I'd like to find something under a hundred bucks. PS the Z bar isn't bent. Thanks guys...

usually this problem is due to the wrong clutch fork. Several of the repro houses are selling a second gen fork and calling iy "heavy duty" The length and leverage on this fork is wrong, it doesn't work.

GM still sells the correct clutch fork for a 69 camaro.

Thanks for the quick reply Jim, I forgot to mention the rest of the equation.. ( senior moment ) I am using a Lakewood Scattershield, and a GM stock fork.. I have an adjustable clutch fork ball, how far should the ball stick out???

A .950" thick flywheel needs a pivot ball height of 4.750". If you are using a scattersheild, you'll need to measure and account for that thickness of the sheild for the overall height also.

You can also buy the McLeod adjustable TOB but, I personally like their adjustable pivotball much better.

Do a search on this, many others and myself have posted a lot on this subject.

The length of the T/O bearing will not change the travel at the clutch fingers.
Here are some threads with good info and fixes.

I had the 15000 series Lakewood with same stuff mentioned, as well as the stock style fork as Jim mentioned . Subtract distance of block saver plate(if you have one) from the 4.750 and you should be on the money. I was using the Timken 614018 or BCA 1705C t/o bearing. I am thinking total height was 1¼".
One other choice would be to use the adjustable upper clutch rod from Speed Direct or something like this, but again as Jim mentioned, forks could play a part here.
