[TR] What dizzy parts actually get converted?

[Paul Dorsey]

Hi,
I have a TR4 distributor (model 40795 made in '67) for my TR3 (boosting 87mm 
pistons?).  I have been told that this model of dizzy's acceleration curves 
are necessary for my upgrade in displacement.   Soon after I get my 
professionally rebuilt engine running again, I had also hoped to convert to 
an electronic ignition.  (I still don't know the best and reasonablest price 
brand to buy (?Q1)   What do others recommend?   Also, I am still positive 
ground, if that makes any difference?(?Q2))

However, Yesterday, by mistake, I hooked up my battery straight to the 
points and the flexy, dirty red little wire to the points (inside the 
distributor)burned the wire in two.  My points maybe fried too.

Perhaps the cheapest route is to go ahead buy and install a electronic 
ignition instead of replacing the points and red wire (15$) .  I am 
wondering: how much of the exisiting distributor guts ares reused after the 
conversion to the electronic ignition?  Can someone tell me?(?Q3)

Thanks, Paul Dorsey
