piping configuration along with hose size are you only limitations. the rear exchanger hose fittings are easy to cut, rotate, etc for fitment and welded back on in the right hands.
lots of extra time and expense if you arent an experienced aluminum welder.

I run a SX style x changer on mine. It is a bit smaller, and has 3/4" tubing ends, instead of the 1" on SRX. I just used a pipe reducer and a short piece of 3/4" heater hose. Never had a problem of overheating in last 2 seasons. I think I have another one on the shelf if interested. PM me if so.

Like ottawaair said or a mtn cooler will work also. Depending on what slet this is for a mtn viper cooler will have the 1" tubing.
You have an SRX?
If you have an SRX you could look for a Mtn SRX extension or order a new one if they are still available. Advantages would be the fact that it would accept your stock SRX cooler which has the correct size tube on it and has far more capacity than an SX or Mtn Max cooler. Another advantage is the correct color to match your tunnel and direct bolt on fit which is always nice. Just some thoughts....I've done it just about every way possible.

I used an extension off of a Mt viper I believe and I cut like 2-3" of the back and am using the srx exchanger
I had a SRX exchanger in my old 02 Viper when I stretched it to a 136. I used a Hartman ext. that I aquired from Rich Motorsports. Cut the ext. down to a true 136 and reinstalled the cooler with the supplied hoses from the ext. kit. Worked great
