so i found a 1500 V8 similar to age to the 3500 i own, but it (among other parts that the 3500 is needs) has Air conditioning, so the question i pose to you gentlemen can the hvac system from the 1500 to the 3500?,

Also does the 1500 use the same TPS as the heavy dutys to run the trans? -

'91 250 4x4 auto bone stock - body & filter mods to come
'94 3500 4x4 auto - BHAF filter

the HVAC system should interchange.

Not sure about the TPS. -

im gonna assume your refering to your 91, no the TPS wont work, gas TPS is 28 bucks, the diesel TPS is 200 at the cheapest, replace it with a potentiometer, its a normal modification......AC compressors are different also..... -
