Will any more comfortable seats from later models bolt in to my gen 1 wagon and brat?

no bolt in seats. sorry. not alot of room in there for legacy seats, or anything bigger for that matter.

i think that the tracls might swap out. your best bet would be an ea82 seat, gl-10 seat, rx or xt seats!

i remember qman saying something about loyale seats fitting into EA81s..

on the 78 brat, having no parts, we are FORCED to explore the option of ea81/ea82 suspensions, and of course, ea82 seats. that is because these are the ONLY parts we have to put it together.

Are you looking to stay Subaru? I removed the seat tracks in mine and drilled & bolted them to a 90 Topaz seat. Very comfy & fits fine.

and noone has mentioned in here about MY SEATS?????? I have some seats from a 86 3 door in my 76 and they are alot more comfy than the thread bare seats that were in there. I used some bar stock and made adapters to fit the seats on the rails. If you want to you can come over here and see them sometime
