Rb26dett crankshaft timing gear

Is there a difference between a rb20 and rb26 crankshaft timing gear as they have different part numbers.

Rb20 part number: 13021-42L11

Rb26 part number: 13021-05U10

Some guys on eBay are selling the rb20 gear 13021-42L11 saying they fit rb20,rb25 and rb26, is this right? 

I need to replace my gear as I want to fit a spool imports spline drive oil pump gear.

Any help would be appreciated. 

Cheers.

The first picture is a RB20/25 crank gear, the second RB26 crank gear. The diameter of the raised face on the RB26 crank gear is a few mm bigger than the RB20/25 crank gear, other than that there aren’t other differences. This may have something to do with the RB26 crank bolt being torqued to 450N-m as opposed to the RB20/25 crank bolt that only gets torqued to 150N-m, that's the only reason i can think of them being different.

      yeah I've never understood that either.... And to answer an earlier question, I write the date on open bottles and throw them if more than 12 months old (which they almost always are, because I don't need to bleed them unless I'm changing lines/calipers etc in between)

      Nah, the one that hit the boot was a big steel locker, around 6 foot height, 4 foot wide and 2 foot deep, empty it weighs about 15kg and had about that amount of stuff in it The photo didn't give a good representation of the actual damage, the large ding on the passenger side was about a inch deep, the one on the driver was about 1/2 inch deep, right on the curve, where the inner boot frame doesn't let you get behind it with a dolly Basically the same issue with getting behind the damage on the centre of the boot We could have filled it all with bog, but my OCD would be triggered every time I looked at it, knowing what hides beneath  As for the locker, I did get the shits with it and put it in the scap metal bin, but, I pulled it out and it is now sitting in the garage at home full of car servicing stuff, cleaning gear and random tools, it's going to pay for it's indiscretions

      Whilst I typically don't cheap out on things, if I can save some money, like $1000, on a clean straight panel, that gives me $1000 to spend on other stuff, basically free money really 🤔 🤣

      Is the toolbox that damaged the boot seal the same item that fell on the car during the storm a while back?

      Who are you to deny yourself? I’ve said this many times to myself and apart from getting what I really want, I go quiet for a while whilst working out what I just did to my savings and how will I afford what it cost, then, next payday…
