Trying to figure out which year (or make/model) this 20r intake manifold is from. I stripped out one of the bolts on mine and picked this one up as a replacement for a few bucks. I'm assuming I should be able to use it without any issue.

Here is the intake manifold from my 77 toyota.




Here is a replacement I recently picked up. I noticed the area near the thermostat is different. Coolant sensor?



Comparison shot

 

Dunno what year the replacement came from but just looking at that hose attachment point on the left side of your original manifold I don't think your replacement will work.
The carb mounting points look wrong too

 

Why did you not just fix the stripped out hole??
