Read this thread. Especially Crazy K's post, He is very knowledgeable.

You can not bolt a second gen subframe into a first gen. You can do an L67 and 4T65 but you need the CV tulips from an HD car and there were different size tulips for different car lines so it should be a second gen W-Body.

 

Wiring to make it run is a hurdle, making the gauges all work is a hurdle. This could have been covered in one thread, like this one: http://www.w-body.com/topic/56149-89-grand-prix-complete-3800-drivetrain-and-powertrain-swap/?do=findComment&comment=1249673

I was looking for that one the other day. Google search likes to bring up threads like these and not the meat and potatoes of the swap.

You can bolt the 2nd gen subframe in a 1st gen w-body, I've done it... Suspension becomes a headache though...

The consensus was that the front subframe bushing mounts were a different distance apart but the rear ones were the same.

Do you have pictures of the 2G cradle in a 1G?

 

To OP: The L67 swap has been done no less than 59,493 times. Google is certainly your friend here. Short answer, you need to play a lot of GM legos and start with a W-car 3800 (to make it easiest).

I'll be damned, Miko said his bolted right up.

Gen1 control arms are bolted to the K frame, and our struts are martian. 

 

Swapping the Gen2 frame, doesn't that mean that the whole suspension has to be reworked? 

 

I remember Miko's car... that thing was all modded up.

[Imp558]

I'm going the other way, first gen subframe and second gen everything else.

I still think I should have went this route instead of my 3400 build...

Yes can be done.

-3800 motor and trans from a w-body(mounts are different between the different chassis. Just makes it easier).

-Inner tulip cv joint from Same trans out axle from 1g w

-Wiring harness 98-99 Monte Carlo/lumina ltz, need to mod c100 conector but easy enough

-downpipe from same monte/lumina

-power steering lines from monte/lumina

-heater core lines from Monte/lumina

-rad and hoses from 3800 car

Motor will drop right into the subframe and into the car no issues.

You can use the 2g wiring but you're into more wiring of the c100 connector as they're completely different.

On heater hoses use the ones that match the yr of the alt bracket.

did you all still want a picture of it installed?
