I have a 1964 M38a1 Marine jeep im looking for the rear u bolts it has a Dana 44 the inside height 7.5 inches

Willys Jeep Parts Tech:
Your M38A1 originally takes 640933 U-bolt for your Dana 44.

I have a 46 CJ2A - There are 10 leaf springs and 1 rebound spring in the rear pack. The U bolts are 3" centers and measure 6", inside of the U to the tip of the threads. The U bolts appear to be to short, very little of the long nuts were catching the threads. Can you tell me what U bolt part number would work for my situation?

Willys Jeep Parts Tech:
These will have an overall length tip to tail of 7.25" so you should be all set with them. Email and we can help. Thanks!

what is length of front & rear bolts

Willys Jeep Parts Tech:
Please email your vehicle information and we can help.

Have a 46cj2a that Ive discovered has dana 27rear end instead of a 41. Need the correct ubolts for the rear end , as my set that I orderd when I thought it was a 41....didnt fit correctly

Willys Tech:
You need qty 4 of part number: A575 U-bolts for the rear Dana 27.

What is the dia of the bolts? 7/16 or 3/8?

Willys Tech:
I will have to double check but I believe they are 7/16 like original.

Just ordered a set for rear axle, do you know the torque spec for the nuts? Thanks.

Willys Tech:
The book doesnt specify one. Just torque down till tight.

Will the length of these fit my original 13 leaf springs on my 1953 M38a1?

Willys Tech:
Yes these will be the proper lenght for you.

What part number do I use for the rear spring u-bolts. This is the only one listed for a 45 MB but doesnt show that it fits a 45 in lyour product description. thank you

Willys Tech:
For 1941-1945 MB/GPW you want to use part number: A575 for a quantity of 4 for the rear
