fc5s shift **** to a fc3s...didnt work

hey guys,

so i wanted to change the shift **** of the '89 GTU cause its was more than peeling of and looking bad, to a '87 series shift ****.

unfortunate they don't swap directly cause the '89 GTU is smaller.

any ideas on how i can get my '87 **** on the '89 GTU shifter without changing the whole shifter???

do they sell something to make smaller thread pattern to big an adapter or something

thanks

sorry for the poor cam quality

orginal fc5s shift **** thread which is smaller


fc3s shift **** thread bigger

You're trying to put an s5 **** (m10x1.25) on an S4 shifter (m12x1.50)?

Only ways I can think of doing it is swapping the s5 shifter over, enlarging the hole on the ****, or cutting the s4 threads down at a machine shop/tap and die.

Teflon tape isn't going to anything. The threads are different. Leave the **** alone or switch shifters.

the shifter is 3 bolts. so unless your s5 is a short model then why mess about?

Yes. tephon tape will definitely work. The problem is it is extremely hard to find. I just searched on McMaster-Carr's site and they are out of stock on it. Most people will try to sell you Teflon tape. Do not do this. You need genuine tephon tape. I would scour eBay for the next few weeks - it sometimes shows up there.


About seven hundred fifty three wraps, give or take, will do the trick.

As others have stated, your only other option would be to find an fc4s transmission. Good luck! You are on the right track.

Come On people!..
the Series 4 shifter has a Bigger thread(12x1.5).The Series 5(S5) has a small thread.(12x1.25)
the Best Solution is to just find a S4 Shifter,.The WHOLE shifter..with the **** on it..
Don't do it Half-assed and adapt it,.It doesn't make sense..unnecessary work.(adapter would need to be metric.and I haven't seen one.)
The Physical characteristics of the Shifters are the same,so it won't really feel different IN the Transmission,it will only Feel 'different" in your Hand.(different style ****).

Saw the title, let thread marinate, came back to actually read it and got some grade A sarcastic entertainment from it. Thanks guys, I needed the chuckle.
