Thank you...I did not know that...that has to be what the issue was then. So now my question to shinoda is does your vette have power seats or not?
P.S. I tried calling you twice now but it goes to voice mail. I need to touch base with you to get these swapped out....please call me or I will continue to try calling you.

FYI My car is a 81 with power seats and the crossmember that you sent me worked perfectly.

Thanks for the kudos...I do try to take care of everyone as best as I can.
The thing about driveshaft balancing is every machine is different. If you sent me one from your local driveline shop that they check out as balanced, my machine will say that it is out of balance. Same goes for a driveshaft from us. We can make the straightest most perfect driveshaft with .000" of runout and send it to another driveline shop and their machine will say it is off as well. Every machine is different. I still don't understand it.
As for the yokes, to my knowledge we are not sealing the caps anymore as the issue was supposed to be corrected on the last batch of them we just recieved. It still wouldn't be a bad idea though just for insurance.

Richard, the reason for the above phenoma is ground vibrations....
from passing truck traffic or construction gear in the area....
it was explained to me and a buddy some decades ago by a NASCAR engine builder back in the day.....he allways worked at night like 3 am, cause traffic was minimal, most really big league shops are out in the country way the hell away from any traffic, and they still work at night....strange but on samples of two over my lifetime they both had the same work habits
it makes sense, in that if you are balancing something like a bottom end or a driveshaft...you have this ground vibration that not all can be removed by just simple suspensions of the machinery...it can toss off a reading....
crazy, I know....but I beleive the old man....

I have an '81 with power seats and the "H" beed in the floor pan.
I have the 5 speed manual kit, and I'll be installing it in June. The distance from the tip of perch to the back of the crossmember is 7.4375 inches (7 & 7/16). I sent you a pm with the part number on it. I bought the kit back in feb of this year.
do I need a different part?
Thanks,
Stephen

Stephen:
After seeing your last post where you confirmed you did not have the rib plus the fact that you just got the kit this year, I believe you should be fine. Just to make sure, check out my pictures I posted yesterday of what the revised cross member looks like and compare it to yours. On the top of the cross member, above the perch, there should be a relief cut into it(see my pics). Also, when I measured from the back of the cross member out to the end of the perch it measured 7 3/4". Double check your again and then let me know. I would like to get you squared away before you start the install.
I owe shinoda a big apology. At the end of last year when we made the revisions to the cross member, I pulled a report of all of our 1980-1982 corvette kits and contacted everyone to get the cross member swapped out. Some how, I must have missed you and never called you. Becuase of my mistake, you are now in the middle of the install and have come to stand still. For that, I am sorry.:o Please accept my apology and know that I will do whatever I can to make it right.

That was your picture I drew on.
but mine does look exactly like that... I was getting a bad measurement reading because of the 1" height difference between the top of the perch and where its welded to the top of the crossmember (it shifted my perspective of where the back of the crossmember lined up with the measuring tape)... it measures correctly.

OOPs...didn't realise that. My mistake. Anyway, like shinoda said...if your's looks like that one in the picture, then you are all set. If not, let me know and I'll send the replacement a.s.a.p..
shinoda...thank you for the compliment but it's not that unusual for me, that's just how I was raised. You can thank my dad for that.

Hey Richard,
I am seriously considering a 700R-4 to TKO-600 conversion in my 74 BB coupe, and I would probably bring the car to your for the job. My question is about my existing Bowtie Overdrives tubular crossmember. It was obviously designed for an automatic but I have read on the forum where some have modified it slightly to use with a manual. I like it because it tucks up under the floor pans on each side which allows room for my custom 3" exhaust. Can it be used with your TKO-600 conversion? If not, will your crossmember clear my exhaust? Thanks.
