4.2 kickdown lever

the 24 spring kit will help elminate the shift overlap....or cheaper ATi has a correctly wound spring for sale 29 dollars i think or mrrandy who list tranny parts for 904/727 over at Moparts...30 dollars......He has alot of billet pieces for sale...
Agreed, but afaik a lower numbered lever further improves the timing. 3.8 or 4.2 was recommended in the instructions with my tranzact brake. I have gone to 3.8 but I have a lightweight drum
and sunshell.
