after all the sierras ive owned,the rear chassis legs is the weakest point

ive seen so many cossies with this,although yours is pretty extreme to be honest

people even bond plates on top and underseal to sell them

ive had one that needed welded,but i couldnt have a car knowing that so sold on,the reason i bought my 3 door is they were solid and untouched

if i was you id weld it and punt it on

youl be lucky to get a sierra in scrappys these days,unfortunatly most were bought for banger racing
