Re: More on Disk swap on 72 Gremlin

Thanks a lot Ken! I'm pretty sure this settles it. The Concord likely got the vented rotor sooner (78 was the first year for the 2.0L in the Concord) because it was a bit heavier than the Gremlin. Nowadays (is that even a real word?) the only solid rotors are usually on the rear, with only a few light weight vehicles with solid front rotors (like bikes, but most of them are grooved or drilled -- as much for looks as performance in some cases). I saved the messages. Will go through them later and compile a chart or list.

NP Frank. and I do not know why my message posted twice. at different times, no 
less. I had sent a long message on this subject with all the part numbers on 
sunday night, and it didnt post, then again on monday night, and it didn't post, 
then this shorter version today, which posted twice. anyway. I  wnet ot my dads 
house to check my earlier books  back to 59 that I have stored there, and 
checked the 73-78 parts catalogue. The 77 gremlin- 40 series and the 78 40 and 
01 concord series all have the same part number for the 4 cyl rotor. And it is 
different and DOES NOT sub up to the 79/80 4 cylinder rotor. I did not check 
81-83, but i think they must be the same as 79/80. The GM 4 cyl came out in 80 I 
think. I can not remember at this point. I do know the new amc 2.5 4 cyl was put 
in some 83 eagles for sale and testing purposes, prior to them being installed 
in the  fall of 83 in the new 84 XJ, but eagles had diffenet brakes anyway. 
Also, based on my AIMCO brake book, the 77/78!
  gremlin 4 cyl (2.0 litre Porsche/audi motor's rotor is # 5105. the 78-81 
concord/79-81 spirit rotor is 5112. I wonder what the wagner or raybestos books 
say. Some brake systems were different if they had styled wheels. Regards, Ken
