I Just bought a 79 brat with the single range trans and was wanting to know if the dual range is a direct swap other than the interior console and shifter? Will it swap over with the same axles and driveshaft?

also are there any things i should know about these cars quirks?

PS- Im new :) I will introduce myself and show pics soon

most likely not if you want to keep the 1600 ea71 engine... the only Gen1 to come with a D/R was an '81 GL. and it came with a 1800 ea81 engine, along with the different engine crossmember that shifted the steering column to Rack juntion so the ea81 would work okay.

you've got a top mount starter. the most commonly found D/R have a side mount starter, which means you'd need a side mount bell housing, but hose only came on the fat-case ea71, which started in 1980 I think. so if yours is the original motor, then it would be a "skinny case" ea71, and won't work....

the axles will work on either tranny.

a new driveshaft would be needed I believe...

So its probably not worth swapping everything over? Is the 1800 and the dual range that much better to make it worth it?
I think i can find everything out locally but i dont know much about them to know if it would be worth all the work?

Yeah that is true, I guess when it comes time to do something fun with it i might deal with it. i was just thinking if it was something that would swap over i could go ahead and do it. Thanks for your help man!!
