I am currently in the middle of redoing the ac box in my 74 maverick and when I took everything apart this rubber grommet that fits around the evaporator core lines and seals around the hvac box crumbled to pieces and I was wondering if anyone had a suggestion on where to look for a replacement or how to go about making something that would work
Not really a help here, just an FYI .... When I redid my A/C box, I used a gasket kit for a Mustang (71-73 I believe) but I don't recall it having that piece. I think mine might have still been OK. Most all of those gaskets and foams worked for the my box and I only had to fab up one or two. This would probably be hard to locate. Maybe it could be a great project for some high school kid with access to a 3D printer? Glue this one back together to use as a model?
This link will take you to the closest thing on the market. With some time and patience, it can be cut to fit..... https://originalair.com/69-73-mustang-evaporator-fitting-case-grommet
Thank you its at least a start I actually have a new unrelated question about the squirrel cage, I pulled the one off the old blower motor and it bent slightly taking it off well I bought a four seasons 35611 to replace it with because it was suggested for it but ive also seen it mentioned on a couple other threads, but it's slightly smaller and oriented the opposite way. So my question is should I run with the slightly warped one ive powered it up a couple times it doesn't have a noticeable vibration but I can visibly see that's it's slightly off while its spinning or run the reversed cage?
I don't know that a reversed fan cage would work well. I just checked Rock Auto, and it is more bad news ... no fan motor or cage for factory air for a 74. I got a fan motor from them probably 8 years ago on clearance, but now they don't list anything. I would try to locate part numbers and search that way if possible. I would bet there is crossover to a Mustang or other Ford part.
A reverse angle on blade will be pulling air in vent(s) and blowing it outside, send it back. With the small size, won't be very efficient if blades were correct. Truing a squirrel cage is usually simple. To find point it's bent outward the greatest amount, spin by hand while mounted on motor (a dial indicator is a big help but not absolutely necessary).. Mark the most outward point with a sharpie or similar. Cup hands around cage, apply pressure at marked point to move cage toward center, recheck & repeat as necessary.
