I need to replace the dashpot in the accelerator linkage of the Holley on my 1968 GT500 KR. Many of these dashpots look similar, so I was wondering what the correct part number was before I go buy something and it is incorrect. Thanks Steve
You might want to straighten out the return spring and bracket as well. They are not correct for a KR

The 428 cobra jet dashpot is still available from Holley
Thanx, Pete. Several questions to get this right. 1) Do you have the Holley PN for the dashpot?
2) Is my bracket correct, and just bent, or wrong all together? 3) Ditto the spring. 4). Got a PN for these from a vendor of your choice, so I'll get the right ones? thanx, steve
Your dashpot and bracket and nut all look correct to me what makes u think its wrong?
No I dont have the Holley part number for the dashpot.
Whatever problem you think youre having the dashpot probably wont solve it
Bill Mansfield sells those for $40 so if you want to spend the $$$ thats where I would recommend going
The return spring bracket is incorrect in every way. Its the wrong shape size and mounted incorrectly. There is no reproduction. The spring looks correct, but it should not be connected to the linkage
Ford part #s are c8oz
Its on Bills website as well.

To try and help Steve with clarification I believe Ed is referring to the the dashpot bracket which is correct and Pete is referring to the the throttle spring bracket which is wrong.
OK, I'm really confused about the return bracket; if it's not available in a repro, does anyone have one they want to sell or loan me so I can have one made? Also, can someone post a couple of more detailed pictures of the spring and its mounting locations? I need to be led through this by the hand! Prior to my ownership, this car had won the Gold Crown 3X, so not sure why the bracket would be so clearly wrong. (yeah, I know, it's been a few years + several mechanics!)
thanx steve
Here are some pictures of an original bracket

In a related question... is the throttle rod really shiny/Chrome or no?
Thanks
Pat
Looks like maybe a potential vacuum leak due to the cracked rubber cap/plug on fitting next to the coil.
Clamp on fuel filter hose should be crimped style or at least have sharp corners.
Not chrome, steel
Thanx for the info; the pictures were most helpful! Any thoughts on how I get sucha bracket? FYI, I swept that area carefully with a propane torch (Yes, Mr. Smarty-Pants, unlit!) no vac leak. thanx steve
I found the bracket on eBay, and you say the spring is correct. So, I should be good to go. thanx steve,
