King ping thread is destroyed, are all thunder trucks the same?

well, i was tightening my trucks and replacing my bushings, and basically on my thunder lights the thread on the king pin is like wrecked so i can't put the bolt on, so i tried to take the king pin out but it wouldn't come out, so i hammered it and still it wouldn't come out, it was completely stuck and the fact that i hammered it the king pin is completely wrecked. so i need a new one but i can't get the current one out, and i've if i did i wouldn't be able to get a new one in. so now i can't skateboard, so im wondering how to replace this, i think my only option is to but one new thunder truck for �15 and take the base and the king pin of that (which are then put together) and but my other stuff on that base and king pin, bu are all of the thunder bases ( i'm not sure what they're called but the bit that touches the board and you can ut risers between it and the deck) the same? because i know they're not all the same with different makes ( i tried to take the base and king pin off my element trucks and do the thing were i put all the bushings and main metal ( the thing that you put the wheel on ) but the main metal thing didn't fit right), so is the base off other thunder lows the same as the ones i got (thunder johnson lights) so i can take the base and kin pin off that and fix my board? or is it not or are there other things i can do (the new trucks option is about �15) but i cant re thread the king pin because i've hammered it and its all messed up. so any halp?
