I beleive all 1st gens have the "hole" for the thread in type heater. All my 1st gens have it. Most rotaries just have a thread in plug instead of the heater.

 

My shop is gonna setup a little patch of cement for my vehicle, its going up on jackstands and is going to have a car cover over it for winter. My car has always been kept on a cement surface and has hardly any rust (i think the first owner may have drove it a winter or too cause there a little rust spot thats visible on the inside of the car (if you lift the carpet) but other than that its mint (in the rust department)

I was thinking about storage, but when my shop offered i couldnt refuse

 

slorimer, I'd be interested in one of those thread-in heaters for sure. How much would you ask for one?

 

If it got that cold here, id freaking move Hell with that
