trying to put bed back on truck

[jasonroman]

so a while ago i decided to take the bed off and do a little body work.
when taking bed off, bolts spun and then i needed to cut them off to get bolts out and bed off.
ordered new hardware..lmc..
and now only the 2 long ones are holding down my bed.
so 2 out of 8 are working.

what should i do to get the other 6 to help keep bed in place?
thanks for any possible help here fellas.

no welder here so tacking the heads in place will not be an option. unless thats the only way to solve my problem, then ill need to take truck somewhere to have it done.
if so, should i fear bed moving in transit??
