I need a distributor vacuum advance for my 78 hilux but the only ones on eBay are for a 2.2 corona will that work on mine

 

I have a stock distributor for a 77 pickup with a 20r, I'll dig it out and get some pics for you later today

 

i have one in a 81 you can get for 30 shipped

 

I put the whole internals out of a 2.2 electronic dizzy in my 18rc dizzy so I would guess that the vac advance unit is the same.
