1969 F100

I recently purchased a 1969 F100 with the intent of restoring it. I was told by the prior owner that the engine was a 390. It also has a 4 speed transmission in it which I was told was from a 1965 Mustang and the rear end was from a 1966 Mustang. I am trying to confirm the engine size, transmission, and rear end but all of the identification tags are gone. Is there another way to ID these parts?

I have some info on my website which may help you ID your engine and tranny. The rear-end ID will be harder. If you need any help, just ask.

Let's see, the largest V-8 engine in 65 and 66 Mustangs were 289s. And, except for Shelbys, the rear axles were 8 inchers. I wouldn't put alot of stock into the info you have to date. The easiest way to tell a 8 from a 9 inch Ford rear is if you can put an extended socket onto the bottom flange bolts. If you can, it is a 8 inch. If you can't (only can loosen the nuts with a box-end wrench), then it is a 9 incher.

Well ole65, I tried your test for identifying the rear end in my '69 F100. The extended socket fits on all of the bolts. Can I now absolutely confirm that it is an 8"?

Thanks for your help.

Yes and no. It is not a Ford 9 incher; but it could be an 8. Since it has been changed, there even is the awful possibility (but unlikely) of having a 7 1/2 inch axle from a six cylinder car. Horrors! I really didn't/don't know that Mustangs had the same axle width and spring perches as the pickups. But there are a number of Ford vehicles that it could have come from. Oh yes, one correction. 289 Hi-Po also had 9 inchers --- also rare. There is also the possibility (more likely to me) that someone stuck a non-Ford axle (Dana as an example) under there from a F150 etc. The way to tell those is an axle tag, stamping or get a manual with picture I.D.s of the housing cover (they have different shapes).
