Well. What it takes to do the conversion really depends on who you ask,
who does the work, or what your willing to risk.  If you have an AC
place do the work, then most likly they'll tell you they need to replace
pretty much everything.. as they're after your cash.. (at least all the
ones i've ever had dealings with have been like that). From the
conversions i've done, and seen done.. Your probably best off replacing
the accumulator (especially if you allready have one) to eliminate any
r12 contamination, and the orifice tube. Though to be honest i've seen
at least one conversion to 134a that NO parts were changed on.. the
system was simply put under a vaccum then charged with 134a and ester
oil. As far as I know it's been working at least 3 years now so far with
no problems(after the original leaky connection was fixed)
.
On an AC note though.. When I get that far with my D as to needing to
worry about the AC system.. is there any reason why I shouldn't just
convert it from it's original bottom connector accumulator to one of the
later side connector versions since i'm planning on replacing the nearly
25 year old AC hoses anyway? (i'll be replacing the accumulator anyway
since i'll be converting it to 134a.. and $30 for one of the later ones
sounds much better than $150 for the bottom fed ones the 81's had up
until whichever vin they changed it)
