The 4bt was manufactured with several fuel injection pumps. The 4bt is manufactured with no method of attaching a transmission, an adapter plate is needed to connect the 4bt engine to a transmission bell housing.
I have no knowledge of what injection pump and transmission/bellhousing the Venezuelan Ford truck has.
Consider using an engine and transmission from a Venezuelan Ford truck. That way, you would not be searching for adapters to attach a random transmission to the 4bt engine. In North America (USA and Canada), we have options that are getting harder to find - In your case, these options also would be expensive to ship and possibly difficult to import into your country.
The 1986 Ford F150 (see my signature below) - My 4bt came out of a 1986 Ford E350 (bread van) and had an adapter to a common Ford small block V-8 bellhousing pattern. I was able to bolt a 5 -speed overdrive transmission to it.
