Hey guys just joined the club this week! Finally got my grail! But she is in need of some pretty significant TLC. Its a re-import from Germany. At least thats what the currency taker is showing me. Check the pics out but there is some water damage on the bottom of the cab and on the back box. The PF is going to need some help and the backbox GI is partially working too. Then I get to see what other surprises are waiting for me! I might be limping in, but hey I'm in! Finally!

(Oh ya I'm in the Shadow club too )

Need some help looking for the hardware (correct) that goes in the spot where the T nut should be at. Thanks in advance.

That is correct I think it's a 6-32 but I'm not 100%. I also need to know what type the bolt is that secures to the T nut.

Im thinking this is the stud just need a verification,

Thanks I appreciate the help! I was not planning to put a post there I realized later after looking at it that was the wrong part that I was thinking of. I think you are right it is a 6 or 8-32 T-nut and then from what I've gathered there is a 1/2" (length) hex head bolt that then anchors the motor base to the underside of the PF right into the T-nut.

Absolutely! Thanks Bro!

I'm having an issue and hopefully someone may be able to shed some light on this. My trunk is not turning and if and when it does it is sporadic I get the trunk error but then when I go into the trunk test it will not respond to command via the button input. I have done the leon fix board and cleaned the gearbox and added a new motor. I also just replaced the U3 and U4 chip on the motor control board and I see 12v and 5v where I should there as well as 12v to the motor. Really stumped at this point. Any help is appreciated.

Thanks!

Thanks for the response! If I'm understanding you correctly by old board you mean the opto board? The Leon board is a piggy back to the new opto board that's on there now.

I have tried by passing the Leon board and I get the same result. Also I checked Q40 and Q42 (Left & Right trunk control) transistors and pre drivers and the BR's since I was there and no issues there either. All were within .4-.6 v.

As this method maybe an easy fix; a cleaner version would be the leon board fix. I have it in my game and whenever a ball gets stuck up there (or any stucky) and the game goes into ball search the board tells the motor control board to spin the trunk the opposite direction thus effortlessly and seamlessly putting the ball back into play.
