Since we don't have the exact kit you need you'd have to piece the kit together that you need. For hangers you'd want the pat # E4139 which is 4-1/4 inches tall like you mentioned needing.
For 2-1/4 inch long shackle straps you'd then want the part # 18-11GALV. For the equalizers # TREQE1. And then for bolts # 126B2. view full answer...
