Problem with swap of upper drive and helmet. Bolt size is different?

[keithc81]

Volvo AQ170 / 280

I am swapping out the steering helmet and upper drive after a u-joint broke and took them out. The used replacement parts I received are a little different where the helmet bolts to the upper. The bushing on the original helmet seems fixed in the helmet and in the new one the bushing just floats in there. The bolt seems to fit in both helmets just fine but the bolt size is much larger on the replacement drive so using the old bolt is out. Just wondering if anyone knows what bushing and bolt to order to match these up. I can get the part or serial numbers off these parts if needed.
Thank You

Bushing slides right out of this one

Bolt too small for new helmet. Hard to tell because the threads don't start till halfway in on the right one but the bolt hole is much smaller

I did some more searching and found that there was two styles of the single bolt setup. One has a 1/2" bolt and the other is 18mm. Now I just need to find the 18mm bolt and the bushing the matches this helmet.

Did that housing break from the busted ujoint?

Yeah this is how I picked it up. The bell housing, steering helmet, and upper drive unit were all busted up.

Have a look at this link. I shows two different bushing setups. Hopefully, you can figure out which one you need.

Looking at those diagrams can be a real pain. I have had to google each part number separately and try to find a picture. So far I have found the correct bolt but no luck on the bushing. I may just reuse mine since its not terribly worn and its not in that hard of a place to get to if I want to replace it later. Thanks for the help!
