The new Happ heavy duty trigger sticks uses a 20 pound grommet.  The -20 in the description is the forced pounds. replacement grommet part below

So that right there is a huge difference between the old school & the new school parts :)
That would feel sloppy if that was placed in a Tron stick, the new happ grommet part. A 15 pound difference.
And you would need Hulk arms to play Pac in a Tron stick.  ;)

Huh... I never thought about that for my GORF sticks. I wonder if those use the 20lb or the 35lb grommet? How can you tell?

 I'll have to look again, but I believe mine are begging to be replaced. Anyone making the 35lb part?

I do know Gorf used the same modified grommet as Tron did.
So even thou the new Happ heavy duty trigger stick grommet will fit in there, same mounting holes. It would feel sloppy in there.
There was more technical info on the grommet than just the service manual had. As in part #13 in the service manual. (pics)
Well you will be lucky here with in the year.  G3N3R1C (KLOV) was not going to do any more reproduction runs of the grommets. I had lucked out & got some both runs he did, in my pics of post. But I spoke to him today & he will be doing another run of those grommets.
But here is what he said about the 35lb resistance,

"The 35 pound throw was not arbitrary, I had a few NOS samples tested by the manufacturer for actuation force then stumbled upon some Midway technical docs confirming what they had told me."
 So here is his site, he does a pre order & then has a few left overs.  Both go fast, so when I hear of the new run I will let you know. :)

Interesting. I don't recall a parts list for the Gorf stick. Schematic and IC list, yes. Parts list, no. I will check as soon as I get back to the dev computer.

SavannahLion:
Yep. It's right there on page 22 of the Gorf service manual. Same grommet. Same part #.

I knew the sticks were based off the same hardware, but I figured the grommet was different due to the gameplay requirements. Much like how Gorf uses a custom PCB and optical sensors instead of switches. Nice.....  ;D

I would love to get new restrictors. It might goad me to fix the cracked PCB and maybe give it a modern upgrade.  :cheers: I found soldering 0603 resistors not too difficult. ;D

Thanks for the photos tron84. That clears it up for me. I wish someone would produce a stick like that. I guess the Happ Heavy Duty is the closest it gets. I can't justify the cost though.
