Repair of FEBCO 765 Backflow valve

<font face="Comic Sans MS"></font id="Comic Sans MS"><font color="navy"></font id="navy">
[:(] I hope that this is the right forum to use for this question ?
Hi All, a few weeks ago my FEBCO 765 Backflow valve/Pressure Vacuum Breaker did an internal self destruct.
We had a mild freeze and it might have frozen, but I have had problems with the poppet for several years now. The 765 casing looks ok.
Anyway, I need to get internal replacement parts (all of them) for the 765.
I measured the incoming water supply line and it was 1.3 inches so am I right in assuming that I have a 1 1/4" model 765 ?

From looking a FEBCO 765 parts breakdown sheet - it looks like these are the parts that I need.
905-212 Bonnet/Poppet Kit
905-052 Check Assembly Kit
630-106 Check Spring

The real question that I have is -- Wouldn't it be cheaper if I just bought a 1" FEBCO and took the parts out of it to rebuild my 765 ?
Are there any plus's or minus's in doing this ? or should I just purchase the rebuild kits listed above ?

Figure you have a one inch Febco - inch-and-a-quarter PVBs are rather rare.

With my experience on Febco parts, you could but a second home for the same price as the replacement parts. Febco makes a quality product, but are often priced way off on the repair parts. My suggestion is to just get the parts, or better yet, purchase a Watts PVB (model 800 series 1"). The watts are less expensive and are way cheaper for the replacement parts, especially if this were to happen again.
