M101A2 surge brake assembly, front rack
 

I have a Canadian manufactured Manac M101 trailer.
Time to give this time of girl some tlc.
I am looking for a surge brake assembly as mine is pretty bent up, seized and broken.
The M101A2 trailer uses the same item.
Also looking for a front rack one piece section. Mine has a two piece which I do not believe to be correct and it's in bad shape anyways.
Would also be interested in the correct tarp for same if someone can point me in the right direction.
