In a 1969 Satellite, is it correct for a 742 Sure Grip or would it have been an 489?
Thank you,

ANd depending on the engine and options (or lack of) it might be an open and not a SG.In a 1969 Satellite, is it correct for a 742 Sure Grip or would it have been an 489?

My husband was looking to change out his 81/4 rear end for a SG. He didn't know which one would be correct for the car.ANd depending on the engine and options (or lack of) it might be an open and not a SG.
The build sheet will tell what was correct for it....if one is still with the car.My husband was looking to change out his 81/4 rear end for a SG. He didn't know which one would be correct for the car.
Does he have a 8 1/4 or 8 3/4 Both rear ends but completely different in design.My husband was looking to change out his 81/4 rear end for a SG. He didn't know which one would be correct for the car.
I'll take a 742 clutch over a 489 cone any day of the week. Nothing wrong with a 741 either..
In the 80's and 90's I would sell all the clutch units because I could get twice the money for them and kept the cone units for myself. Same with the 41's because everyone thought they were junk. I know how to fix a slipping cone unit pretty easily and never blew up a 41 3rd member and I tried lol. In fact, I had more trouble with the clutch units than I ever did with the cone type. It was harder to get a clutch unit that was a bit on the tight side to quit chattering than it was a tight cone unit.....1969 came with a 489.
742 is the best.
a 489 is the last one I will buy if I’m shopping for one. They are Ok and I will use one that works fine, but they are not the best one.
It is an 8 1/4, 318 engine. He is deciding whether to put a 383 the car or keep the 318 and put 340 heads and intake on.Does he have a 8 1/4 or 8 3/4 Both rear ends but completely different in design.

There are sure grip options for the 8 1/4. but your original question is mute as you have an 8 1/4 not 8 3/4. QUOTE[[[[[In a 1969 Satellite, is it correct for a 742 Sure Grip or would it have been an 489?]]]]]
Now, I have another question. Will the U-joint on the drive shaft that was for his 8 1/4 rear end bolt into the yoke of the 742 rear end? Also, will the drive shaft be the correct length? Keep in mind, presently 318 with 904 transmission going into an 8 1/4.
Don't tell everyone the price will go up. LolI'll take a 742 clutch over a 489 cone any day of the week. Nothing wrong with a 741 either..
There's been times when I got new plates etc and they were not the same thickness as factory replacement parts. When I had factory replacement parts, everything went fine.In a clutch type the plates go in a certain order. See the Service manual. If you don’t do that they are too tight Amd. Pop amd chatter. I thought I could let it wear in. LOL it broken the spider gears. Learned this the hard way.
When done right the clutch type has worked just fine for me.
After all these years I would think everyone (or most everyone) knows.....Don't tell everyone the price will go up. Lol
