Hi Guys - instead of selling my damaged C170B I've finally decided to rebuild it...wish me luck - Vic Prefontaine has 70 years experience in metal working for Air Canada and Perimeter and has kindly volunteered to provide guideance, instruction, and help!!! He deserves a gold medal for patience . The rudder and aileron fin is now repaired, all of the other parts are undamaged and hanging on the hangar wall. Now focusing on the fuselage - unrivetted the firewall - wow it looks better already, removed the crumpled forward floor panels and have started on the consol and floor panel that covers the gear boxes. Where do i go to buy two new gear boxes? Any tips on installing. I have contacted P-Ponk but they just have reinforcing parts not the whole gear box and I did an awesome job of crumpling both - especially the right gear box. Thank you for any and all advice/photos/sources on this....lookinig at it positively there are tons of panels that are still beautiful, a few that are crumpled pretty good. Am going to put an O360 Lycoming in, found the STC for the IO-360M1A,B engine does that have to be fuel injected ...not sure about the difference between A, B?

C-GGPI is coming back to life
I think you'd be lucky to find a NEW gear box, and I'd hate to guess what it would cost, but you should be able to find a salvaged one. Del Lehmann at Mountain Airframe in Mena, AR should be able to point you in the right direction.
Jill, I hate to give away my known stores of resources but then again it's about the plane and you are a long standing member. Pls PM me your email, I know I have it at home but I'm on my way to an out of town Xmas party.
Firstly I haven't been eating yippee beans and no smoken Mary Jane , but have been told that a Cessna 206 gearbox will fit. Or slightly modified to,suit. So I,would be doing some research and running the tape over a Cessna 206 gearbox. However the source of this information is now deceased so I can't check out from him how he came to this conclusion .
The source of my information regarding the gearboxes of the 170 and the 206 is deceased but will try and find his business partner who would have some information on this subject . However the gearbox of the early 180 ,s and the 170 should be similar also . I would be running the tape over both .

I heard that some of the early 172s were drilled for the box but didn't actually have it installed.
It'd be a worthwhile investigation to find out as gearboxes are tough to find.
A similar rumor circulated with respect to early C182's. While the bulkheads were pilot drilled for the gear boxes, the boxes themselves were ever actually installed.
You might call up Stoots Aviation in Fairbanks. He has been doing tailwheel conversions on 172/175s using new 180 gearbox, 180 gear legs, and P-ponk kits. He must have a source for the parts, perhaps you can convince him to share.
36 years ago at the Ithaca Convention in NY. the gearbox was number one 1 on John. Benhams want list.
In detailed requests with Cessna plant they explained that they would have to create and let 14 different contracts with outside vendors.
Tell me more about the 206 gearbox. Isn't that a wide body?
John D. finally found a NOS gearbox and bought it from a closing Cessna distributor. He sold it to Bill Goebel who installed it in N146YS during it's restoration.
John D. inspected the installation when we met at my first Texas fly-in arranged by Louise Bickford at Lockhart, TX. He told me he believed it to be the last NOS gearbox in existence.

Here is another possibility for gearbox parts. I got this about a year ago but they may still have what you need.
