if you changed frt drums and frt pump from originals and mis-matched parts-like we used to do, you could have problems. we used to disassemble trans and save parts and would use a front/rear drum or stator support without checking to be exact same part. we shot ourselves in foot. now we check all parts by measuring individual parts or using all parts that are kept together. john kunkel had/has a pictorial reference of parts that is very good at determining correct parts.get it if you can. also we now air check parts on bench before putting in trans. somethings to remember are very hard but jk's pictorial is very good at helping determine correct parts. would like to see jk put together and sell picture book. would be great reference material. we have also talked to john cope and rick allison on odd ball stuff and those fellows are both gentlemen and very knowledgable. thanks to both and also john kunkel.
