Question:

I have a bull dog slide coupler trailer hitch is the coupler with a swing latch cast iron or cast steel. My spring latch broke and was wondering if it is replaceable or weldable. Thank You

It sounds like you might be needing the Replacement Coupler Cap Spring # BD500354 which fits the Bulldog Collar-Lok Couplers.

If more than the spring is broken then we'll need to get you a completely new coupler. In this case let me know the what your current coupler is rated for and if this is for a straight tongue or A-Frame style coupler and I can make a replacement recommendation for you.
