long story short, will a slip yoke that fits a 1350 u joint that i got for my fbody fit any make of driveshaft as long as it accepts a 1350 u joint? ford chevy dodge etc?

1350 dictates the size of the joint...so yes it should.

what is a 1350 u joint vs a 1350 conversion joint

stevieturbo

no idea....post a pic or link to whatever you're referring to.

A conversion joint has cups and width to fit 1350 cups and width on one opposing pair. The other pair are sized to fit a yoke with another size. 1310, 1330, or 3R, for example.

Are you needing a shaft with 1350's?
I'm about to replace my aluminum one with 1350's on it. Was 4l60e to 9". I'm about 30 miles from you i think

no i have one now but am swapping the 27 spine yoke for a 32 spline for my trans. its just kind of shitty cause rookie mistake, broke in the rear without the rear loaded and put a nice ugly groove in it. kinda hate looking at it. i got it checked and the balance is still fine. id like to get a new one but whose gonna want my old one? probably only get 250 for it. not to mention finding someone who needs one for a 9 inch......limited market there. but humor me, is it a pst shaft? how much u want? i think it should be the same length for my t56

I essentially made a similar mistake and scored my $500 PST DS.

So got another new one from PST, but be aware that even though I specifically stated that I had the stock rearend the DS from PST came with 1350's on both ends. So on the backside you will have to remove the 1350 and replace with a conversion yoke. That will leave you with a new 1350 as a spare.

Since then I have learned that my scored driveshaft might still be salvageable. A local driveshaft shop say that they simply remove and replace the tube. Haven't gotten a price yet, so that might be an option for you instead of buying a new PST DS like I did.

why is that worth it? only reason i ask is because it sounds like ur getting a new driveshaft but not having ur old scored one to sell to someone to recoup some loss......

I'm not trying or wanting to sell anything to anybody. I have already purchased a new PST and it is installed. So now I have two practically new spare 1350 u jointand one spare conversion u joint. But at my yearly mileage it's doubtful I will ever need them.

My point was that getting a new tube might be cheaper than buying a new driveshaft for $500. Unfortunately I didn't know until after buying a new DS that I could have replaced the tube instead after a friend told me it would have been much cheaper to have it re-tubed.

I was also giving a head ups when ordering a DS that if you have a stock rear end, that you will want to make sure that they send it with a 1350 in the front and a conversion joint in the rear.

Of course this assumes that the half joint on the stock rear end hasn't been replaced to accept a 1350 u-joint instead.

stevieturbo

obviously if the joint still use part of a smaller 1310....is it of any benefit as you still have that weak point there ?

Seems a bit pointless.

Now that I think about it...it may be the stocker with a conversion for the 9". It came with the Moser I bought but the shaft is about 2" to short. Its only about half engaged in the trans. 27 spline.
Maybe you or someone can tell me why the stocker would be too short. Is it because of the 9" or is it because my '95 is LS converted and trans sits in a different spot than an LS car, or both?

u need a longer driveshaft for the 9 inch, because the pinion location vs the 10 bolt. the pinion is in the middleish of a 10 bolt, and the pinion on the 9 inch is practically the lowest point of the rear. so since ur lowering that point, the length of the driveshaft needs to be longer. remember in school the right triangle equations involving leg 1, leg 2 and the hypotenuse? as u increase the distance of one of the legs, the hypotenuse now has to lengthen or its no longer a right triangle.
