Donzi Hornet III, BW transmission, TRS drive, I've got a good knocking when I'm cranked hard over, so am replacing the U joints. I saw a post stating that the TRS uses spicer 1320 joints, but can't find any info on a 1320. Does anyone have a cross reference, Are there newer better quality u joints I should be installing? I've found a Sierra replacement, and a replacement that says its a mercruiser part 94-01821,

I suspect you mean the Spicer 1310.

That's what my TRS drove with BW yoke has for U-Joints. With the P161 caps.

I'm going by another post here that quoted the 1320...if you used 1310, then i'll look up the same, thanks,

All the info I found...there is no Spicer 1320. But a lot of older info isn't on the 'net'.

I'm looking at the 1310, it has the retaining ring on the outside of the u joint, mine are on the inside...unless a 1310 comes with either cap, this is going to require more digging

Do the Bravos use the same u-joint as the TRS?
