1300 5 window with the original 216 engine. I am wanting to be able to drive it to shows but the 4:11 gears in rear are a pain. I know that 3:88 gears are available but rumour has it that they will only go into a U S built axle, not a Canadian built one. Is this true ? | | | | | Joined: Mar 2007 Posts: 4,215 Moderator | | Moderator Joined: Mar 2007 Posts: 4,215 | Never heard of that one. My truck is a US 3100, put in the 3.55 rear and am very happy with it.

I think you are correct about people posting something being different in Canadian trucks. Maybe it can be "solved" by using a 47-53 USA 3100 carrier?
Wait to hear from someone who has tried the 3.55 R&P in a Canadian 1300. | | | | | Joined: Feb 2008 Posts: 202 Shop Shark | | Shop Shark Joined: Feb 2008 Posts: 202 | Hi, 7998, I think you mean 3:55 gears. It is true that the US gears are NOT a straight bolt in, but the US ring gear Will fit the Canadian carrier with modification. What I did was take the old 4:11 ring gear and the new 3:55 ring gear to a machine shop and have them slot the new gear to match the old gear. ( Bolt holes are on a different base circle) All the other parts will bolt in. With the drive shaft apart you should replace the front drive shaft bushing and seal assembly and the rear axle seals. I purchased the ring gear set from Patrick's in the US. Also get the speedo adapter from them. I am Very happy with change in gearing. Have Fun, Brian
Keep the 216's running. 1949 1/2 ton model #1314 (US 3104) Brian

The comment about highway speeds requires highway brakes has got me thinking though. | | |
