you will need your throttle pressure linkage with the tranzgo 2 kit

the tranzgo3 makes it a forward shift full manual VB and no linkage,IIRC

or a forward/revers shift full manual vb to replace your stock VB for no linkage

I went with a forward shift full manual low band apply valve body with a billet low/revs servo from CRT in mine for no linkage on the 88-440 truck about 500bones for VB and servo

you are wanting the lower first gear stuff from an mid 80s a999 tranz for your older 904

might want to check with dusturbed340w5(woody) over in kissimmee Fl,he has the low gear sets out for sale and ready to go,I just got a few things from him and he said he has not relisted them yet..shoot him a PM..he a tranz builder also

my local guy i told you about charges a flat 800bones to rebuild a mopar tranz, thats with me bring just the tranz in over the counter and thats a fair price IMHO

what rear axle do you have in your car?

you could use a nice 3.23 or 3.55 for your cruzing in that heavy car with those 22" blings
