32 front spring u-bolts

[Ole Lou]

Put the front axle under my 32 frame today. The u-bolts and nuts bought on-line were said to be 32. the nuts have more points than a standard nut and requires a 12-point socket. There are no provisions for cotter pins and the u-bolts are not drilled for them either. Are these correct? Sorry, unable to send pictures,
Lastly, how tight should U-bolts be tightened-front and rear?
Thanks
