that happened to me once i was driving a friends truck and only the front brakes worked, i didn't know this. i came up on a stop light and stepped on the brakes and with all the weight on the rear the front brakes wouldn't stop it. i was going slow but still couldn't stop, thank goodness the other cars did and just watched me slide on thru. i geared it down for the next one. was a unpleasent rest of the drive. you might make your own. i made one that doubles as the sling on my 64 c20 wrecker. i got the biggest channel iron i could find that fit over the frame and made a custom bumper sling that removes and boom. it is very strong has pulled several trailers and towed and lifted several trucks. i didn't even have to drill new holes in the frame i used the old ones.
