So, I've learned to live without, but as summer drags on again the thought is crossing my mind (such as a mark iv evap from vintage air ). I'm not convinced that it would cool well enough to keep up with the massive amount of heat coming through the firewall.

I tried dynamat and normal insulation with the grey stuff on one side and the silver reflective on the other and got no better result. I ended up ripping it out and cursing myself for getting all of the goo on the firewall.

I was wondering if anyone had put a/c in their 41-46?

If so, what did you do about the heat from the engine flowing straight in the leg area?

and, are you satisfied with the performance?


I'm unconcerned with the cost and logistics of installation. I work on stock a/c systems regularly and have installed 3 or 4 aftermarkets in vintage rides for people. Never done one in something with such a heat transfer problem though...
