    sorry we do not have enough information to guess what bolts might work for you

    will these fit 1/2 thread ? yes

    are there 7 short bolts ? yes they are a UHL of 3.750

    are there 7 long bolts ? yes they are a UHL of 4.500

    do all 7 long bolts have 7/16 stud on top ? no only two of them do

    Is this 7 bolts and 7 studs with 5/8 heads
    91jeepyj December 13, 2016 8:06 PM

    no, recheck your old bolts because 1/2 threaded OEM style bolts take have a hex head 11/16 wrenching

    i suspect that you have a engine with 7/16 bolts those take a 5/8 wrench from the factory
