81 210 to 75 b210 "swap" question

[hurricane14]

so we are planning on taking an a series engine and auto tranny that was gone through not too long ago from an 81 210 and replace the original a series and auto in our 75 b210. anything we should look out for? hoping it should pretty much be a plug and play set up, but have been caught before, so trying something new (thinking ahead).... thanks

i already assumed this might be a stupid question before i posted it, but since i see 46 views and no replies, i guess my suspicions are confirmed.....stupid.....

     mainly was just checking if any motor or tranny mounts, driveshaft yokes or lengths, reverse light connections etc. would need any attention before we got into doing the work. hate to get held up in the middle of something if it can be avoided.

Asking questions is always an intelligent thing to do. Especially when it comes to swaps. I am familiar with B210's from 74-78, I know nothing about the 79-81's. That said, I would think if there is any difficulty it would lie with in the trans swap. If my memory serves me correctly the 74-81 auto trannys are the same unit. But I would not be surprised if some of the electronics were updated.

Oil pans and pickup tubes are different. Will need to be swapped over. 

 

If the new engine is an A15, that brings up another problem.

The 210 will have an internally regulated alternator but you can still use your B-210 externally regulated alternator onit. I would hang onto the internal one and do a conversion later. Also the 210 engine will have an EI (electronic ignition) distributor and coil. Again use your B-210 system for now but keep the EI one and convert it later. The EI replaces and gets rid of the bothersome points.

 

Length will be the only problem if there is a problem with the automatic. The later A series engine should still bolt up to the earlier B-210 automatic is the 210 auto is the wrong length.

datsunfreak and datzenmike, thanks for checking in. that is exactly what i was looking for.

 

 looks like we may finally get started this week or next, so let you know how it goes and if we have any issues.
