Joe, you are correct as I did believe my current carb was a single barrel...I was visually comparing it with the single barrel carb on my old 62 plymouth with 225 slant six engine and was sure it (the 51 Kaiser's) was single also. Many thanks for the clarification.
Bob...the mat in my trunk has seen better years, but will do for now. Always the optimist, I will be looking for sources of parts for this car as an index as to what I may be able to get in the future, regardless if I can pay for it now or not.
I have many plans for this beastie as to upgrades/refurbishment going forward, with time and funding issues being my mortal enemies. But...one does not retreat from mortal enemies, does one?
Willow Run KF has replacement tire well mats available (that part only, not the rest of the trunk mat)...$80 on an Ebay listing that they sent me in email in reply to that thread...let me know if you want the Ebay link.
