This is probably a US car, so it would have originally been FI. Yes, it can
be
restored, but it takes a fair amount of knowledge and background to do it.
If
the heads have been changed you may lack the place to screw in the head
temp sensor, so such a restoration is best done in the course of an engine
rebuild.
The hardest part to find will be a good 69 FI wiring harness in good
condition.
I MAY have one, but I think I already used my best harness for MY 69. The
other parts are all relatively easy to find but will be somewhat expensive,
unless you can find the whole package in a junkyard somewhere. If you are
this lucky, you should consider just making a deal for the whole engine or
car, for parts. Don't forget that there are some relays up front, as well
as the
fuel pump under the gas tank.
The dual carbs used on type 3s were downdraft Solexs, while there was also
a single sidedraft Solex setup which you should avoid. The Dells are
aftermarket carbs.
