Thanks for the offer but that won’t be necessary. I went through parts manuals for the 180 and 172 and determined the part number for the rear seat catch brackets is the same between a 1957 180A, and a 1959 172. I have a friend with a 59 172 and he’s going to let me have the brackets since he put in F.A. Dodge seats and doesn’t need the them anymore.

Here are what the brackets look like from the 170s and early 180s:


Rear seat catch bracket on a 1959 172, same as a 180A and at least some later models:

IPC does ID parts based on s/n.
You'd want 0511285-3 & -4 for s/n range 32151-50355.
I'm assuming that's the one in your second photo.
Looks like an easy (re)install- just bolt her one, no riveting required!

I saw those part numbers in the book also, but I don’t think that’s them. I think the numbers you listed are for the “arms” that are on the rear seat back itself that slide into the bracket I pictured. Look on the figure for the auxiliary seat installation (even though this part has nothing to do with the auxiliary seat) and the part is clearly visible, item 21 part number 0511286 “LATCH ASSEMBLY - REAR SEAT BACK”





Here are the nutplates on my plane where the brackets used to be, I have them on both sides.

You're probably right. That bracket in the IPC cut you posted is sure the right thing for you.
Sure silly to have it listed & illustrated on the aux seat page though.
Hard to tell what's what in those IPC's sometimes.
I was looking at the pdf file of it I have here at home, even worse than the hard version when you're trying to find something or figger something out just by visuals.

Took a look at my hard copy IPC today.
FWIW it looks like maybe the seats are the same early and late,
with just the adjusting mechanism being different.
With the early seats, the adjustment is in the fuselage bracket,
whereas on the later seats the adjustment gizmo appears to be built into the end of the rod (for lack of a better word) that runs across the top of the seat back.

Yes, the seats are essentially the same except for how the top of the rear seats mount to the fuselage and adjust.

I understand that Rob has decided to go with a rear bench seat but I would like to take this opportunity to clarify a few inaccuracies and misconceptions regarding these installations. I had a chance to review the paper work for the Kenmore 206 seat STC today. I purchased this STC and the installation package for my 180H project in Feb of 2017 including the revised drawings dated 7/20/16 (hope to get to this project this winter). First to answer Rob's question the seat part numbers must include part # 1214008 or part # 1200605, both of these would have a dash number suffix associated with them. A float kit is not required but the reinforcement (angle under floor) which is part of the float kit at sta. 90 of the fuselage, part # 0742115-16, 0711089-1 or 0711089-2 is required by the notes of the installation instructions. It may be possible to obtain approval to install a short piece of angle for each seat track in place of the required part numbers as this is where the aft end of the seat track attaches. The notes also specify that the seats be installed in the forward position, so they are no longer adjustable if you want to be totally legal. This would place the forward edge of the seat at approximately the same place as the factory jump seats or the bench seat. You would effectively have more leg room as the length of the seat bottom is longer. The drawings also say to attach the seat belts to the fitting used with the six place seating configuration. If your aircraft does not have them you would have to purchase part # 0711084-15 and 0711084-16 which go between the fuselage skin and the sta. 90 bulkhead on the left and right side. You would also need three part # 0711083-1 seat belt attach fittings in addition to the four seat tracks (PMA'd parts are approved per the drawings) you will have to modify for the seat installation.

As for the weight of the 206 seats, the ones that I have are the short back utility model used with the hard side interior, covered in Cessna arctic fabric and weigh 8 pounds each. I also have a set of Cessna factory jump seats covered in leather and these weigh 12 pounds each, in part because the foam and fabric are attached to plywood, which is attached to the metal frame of the seat.

I am looking forward to having these seats as I believe that they will be much more comfortable than any of the other jump seat choices while giving me more options for seating configuration than a bench seat.

Unless you have or get a great deal on a set of the 206 seats, I do not think they would be any less costly than the other non Cessna jump seat options, mainly because of the additional parts, including four seat tracks, you would have to buy.

The folks at Kenmore were extremely knowledgeable and helpful including a willingness to sell the STC to me before the revision was complete if I need it before it was done. It was revised before I needed it but they made the offer without my asking.

I take this to mean you are saying the fwd edge of the seat is the same for the factory jumpseats & the factory bench seat.
I would disagree. The C180/185 "middle row, divided" factory jumpseat I installed in my old C170 was noticably farther forward than the stock bench. I believe also farther forward than the BAS folding jump seats I have in my C180 now.
