Back up.
Post us a picture and a model ID number. 'later'? front end????
All AG chassie model 3 cyl 4000's had the same front end.. there was no early / late front end. ( there are some steering gear / power steering differences yes. )
Industrial and rowcrops models and SU models had different front ends.
When we see the picture, we will know what you have, and we can go from there.
in 2 posts you have said 2 different things. Here you say right, in the other post you said left.

No problem, I can't help it that you posted 2 different things, then won't man up and say that it was your mistake. I'll have to remember your handle so I can avoid offering any help on any future Ford problems you WILL encounter while caring for and feeding these old beasts.
