Toyota AE91 Distributor replacement

[sura2k]

Hi,

I have a Toyota Corolla XE Saloon AE91, 5AFE, 1498 CC car.
And need to replace the distributor.

My car looks like the car in following link, except the automatic transition.

At the end of the gallery, there is a picture of the engine and you can see the look of its distributor.
OR
It looks like this:


You can see coil...it has a circular surface.

But most of the distributors I found on the internet have a slightly different look:


You can see cover over the coil. It has a different but similar shape... but all the others are looks OK.
Now this type of distributors are for 1.6L engines (that is what ebay/aliexpress says) and I believe my one is 1.5L.

In my distributor there are 2 connectors, with 5 pin and 2 pin.
All the others I found on internet have 4 pin connector and 2 pin connector.

If I found a distributor with slightly different look and if it fits, including connectors, If it is OK to use it regardless whether it is 5AFE, 4AFE or 1.5L, 1.6L....etc ?

Appreciate any advice.
I do not have any mechanical knowledge :(

Thanks!
