I read so far nobody likes off-the-shelf u bolts availible from the auto parts stores.. i dont quite understand or recall why. (i had a bad experience with the local leaf spring guy.. dont want to go back to him)

Was at AutoZone, saw a set that seem to match up okay in size n shape. Before I buy and attempt to put them on.. can somebody clarify if it will suffice.

it measured 7/16” dia, 2-1/2”, 6.5” length (7” actual)

another question, others have replaced the nuts with grade 8 ones, if the ubolt isnt rated the same.. does the rating just default to the lowest part in the assembly? or was it replaced with nylock ones? Thanks ahead of time

Just tried the 7/16th and they are too big. Wonder what the stock diameter / thread is?

If you are looking for used I have a set off a 68.

Take your set to another spring shop and they will be able to make you whatever you want... at least mine did, in like 10 minutes.

You'll need 3/8. If you cant show your face at the local shop, go here. I had good service.

What I bought, but keep in mind it was for an rx7 rear end, but using original brackets and springs etc. But do your own measurements.
(5T38-2.5-R) R05 - 3/8" x 2 1/2" Inside Width $4.50 X 4 = $18.00
(5T3814) (Length: 5 7/8")

We sell these for our reproduction leaf springs and they work fine. https://www.datsunparts.com/2151
