I'm trying to install KYB front shocks # GSA272HD on a 74 TR6. I thought it was a simple bolt on. No such luck. For one thing, the stock bolt on the bottom does not fit the KYB shock, too big in diameter. How do I set up the top of the shock?

From the picture, although you can't tell about the diameter of the sleeve bushing inset with the lower 'rubber' bushings it does look like it has the correct type top and bottom ends.
Sometimes you have either extent or compress the shocks during installation.
Maybe you can transfer the sleeve from the old to the new on the bottom.

How about posting some pics of what you have?

So I gather the old shock is out and you’ve removed the 2 brackets from the bottom of the old shock?

Yes. Old shocks are out. Here are some pics. I thought maybe a machine shop could bore out the KYB bolt hole so I can use the stock bolt.

Those should be a direct bolt on. Mine looked like that.

Problem solved. I bought a set of front shock bottom brackets from TRF. The bolt from the package fits the KYB shocks perfectly! Shocks are installed, way better handling!

That begs the question, what was the difference between what you had and what you bought from TRF?

On the ones you had were the center hole enlarged for a bigger bolt?

Thanks Red

When I removed the bracket bolt from the old Monroe shocks, I discovered it was a hair too big to fit in the KYB shocks. The bolt in the package of the TRF shock bottom brackets were a perfect fit.
