I saw Wolfmans reply, I have a couple of beams, at least 1 V strap, & a couple of the pads that fit on the V strap.
Measure your beam length, DS rod length, & the distance between the holes that the V strap bolts to. Measure from the inside hole across the beam to the inside hole on the other side. Nacra used a bunch of different V straps.
You need a new DS rod, I only have 1 spare & am keeping for when disaster strikes. See my album in the Tech help section for building a new one for cheap. Make sure you install BOTH washers. The rod should be 9/16". You do not need that hole in the V strap, the square pad sits on the strap, held by something like Dow 5200, & the pressure from the DS rod. The rod sits in a hole in the pad. the last photo shows both washers, beam preload, & the pad.

All the holes on the bottom of your rear beam are to give access to the nuts securing the traveller track, they are just big enough to slide a thin socket into. If you undo them, use nylock(aircraft lock nuts & or a drop of BLUE Loctite to re-assemble.
I'm in Canada, if you are in a hurry Dan Berger & Pete B would be able to ship cheaper. They are both trustworthy people. Otherwise I can send it next time I'm in the US.
I would get a used beam, they are not expensive.
One thing that looks different is the front beam tramp groove. It appears yours is riveted onto the beam?
All the beams I have seen have a groove integral with the extrusion. Looks like this; (Image from Bill)

If funds are scary tight, use the old rear beam, you're not racing in the Nationals. I sailed an N5.7 for two years with a definite "ripple" in the front beam. Drill bigger rivets,(IIRC 3/16" is about the biggest that the cheapo hand riveters will pull), or use an aluminum washer, as backing, with the same size rivets. If you use washers make a tool from a piece of tubing or broomstick, with a hole just smaller than the washer close to the end. Put a piece of masking tape over the hole, then stick the washer to it. Start with the rivet closest to the centre of the beam, if you start at an end, they will be in the way as you try to work inwards. Place a nail into a hole, have a helper push the broomstick in from one end til you hit the nail. Remove nail, & manoeuvre the last 1/4" to line the washer up with the hole. For the rivets in the centre, it will be easier to also slide a second wedge shaped stick in from the other end. This will serve to push the first stick upwards against the hull, & hold the washer snugly while you install the rivet. Push the rivet into the washer,through the masking tape, pull it...repeat til done.
The hulls look like they are Cal-I-forn-I-A registered, I assume you're close? Pete B is in Big Bear.
Post any other queries, there are a few 5.5 sailors here.
