Yoke/ universal joint

[Strangy21]

Hi all-
New to BUGA. I'm buying a mates 80 CF Beddy. It's undergoing a blue slip inspection and we are stuck here. It has a 4 speed celica gearbox mated to a Holden tail shaft. So before mechanic will pass blue slip it needs a yoke/ universal joint as the one in at the moment is stuffed. Would appreciate any ideas please.
Cheers

Hi.   maybe if you could find a celica tail shaft and get it cut and welded and balanced to your holden tail shaft but finding one would  be your next problem.  i got to ask why is there a celica 4 speed in it ? . is it a holden 6cyl in it.   maybe the celica yoke is not strong enought for the exta  6 cyl power and the weight coming back thought the drive line as the CF is a lot heaver than the celica car and i would not think the celica gear box would be stronger than a holden  Aussi 4 speed gear box. . in the long run you might be better puting a holden Aussi 4 speed it. and get your mate to ajust his price lower to cover your cost of fitting a Aussi 4 speed gearbox in it.

is it that the yoke is not good enough or is it just that the yoke itself is stuffed ?

from my experience with celica 5 speed conversion you need a yoke that fits the celica box with holden 6 uni joint on it, these normally come with conversion kits but you can probably get them separate from dellow or Castlemaine rod shop .... then it would just need a suitable uni which would be from the holden range off the shelf parts ....

also as far as I am aware the celica 4 speed it pretty much the same as the 5 speed, albeit with one less gear and different extension housing.

Hi all
Thanks for the welcome. So problem is now solved. I have a new yoke/ uni joint welded and balanced to fit the holden tail shaft. Apparently now strong enough to run a V8. Ive still got the Celica 4 speed. I'm wondering if i should put a 5 speed in at some point. I dont know why all the original modifications/ why not have an aussie 4 speed instead of the celica. Anyway im hoping to pick her up Mon or Tues....

Hi Strangy good to hear your problem solved.  a 5 speed  over drive gearbox would be good if your diff ratio is low and you do a lot of hwy driving to cut down on high rpm at 100km`. i think most 5 speed  overdrive gearboxs are about 17% overdrive.   if cutting high rpm down is your goal when driving on hwy you could put in a taller diff ratio in is  other way to go

from what i have read the supra  5 speed is a strong overdrive gearbox
