Auto to manual conversion. If you could do it over....regrets, pitfalls, long term opinions???

I learned to drive ( as most back n the 60's) with a stick! maybe why I SOooo much prefer to bang the gears.

I have always used Mopar 833, 833OD or some 3 speeds. if in good condition, 833 all you ever need. IMO.... perhaps Passion etc are great stuff, must be they are still in business may yrs later/

I too recomment Brewer's . great guys. they too have been doing this so many years.

piecing together a manal system to change over can be a struggle. helps to get everything off the right car, and you or someone be able to work on the trans.

skep419 above hits the nail on the head.
