Weld on tabs Crap. Need advice on front sway bar for 70 Dart with no tabs

My son's 70 came to us with no tabs on the lower arms. I bought some of the aftermarket weld on tabs and bolted on a stock front bar. After about 5 months one of them broke. Cheap stuff, thinner metal than stock tabs. So what I'm looking for is a front bar maybe larger than stock that comes with bolt on tabs. It seems I've heard of this set up for the spool K but is anyone aware of one for the biscuit K-frame? Also I'm running stock 73 front disc with the calipers placed on the back side. Pic is bottom of tab where the end link goes through. Thanks!
