Deaver AAL Help

I was given a pair of AALs today from a 1st gen owner who returned his truck to stock. They are a Deaver AAL part number D10045K73. When I google it, it says they're 1.5-2" lift for a second gen, but I've been reading that some people say these will fit a first gen and are the same as the ToyTec ones for the 1st gen?

Can someone shed some light on this for me? Thanks!

 

Bump. Someone has to know! I think Toytec part number TAC-AL-LA is the same as Deaver D10045K73? I'm going to call Deaver when they open but was wondering if anyone is running this or has run it in the past...

 

Thanks for the response! It's not the progressive, it is the single leaf, seen here: https://www.headstrongoffroad.com/store/p96/Deaver_1.5-2_inch_Add-a-leaf_(PAIR)_-_TACOAAL.html

I found a thread from 2012 saying that they fit, but just wanted some re-assurance/ a second opinion.

 

I called and they didn't pick up. I'll try again in 15 mins or so and post what they say.

 

Update: couldn't get a hold of Deaver yet this morning, but spoke to someone at ToyTec. He informed me that part # TAC-AL-LA (AAL for 2" lift on the 1st gen) is the same part number as Deaver D10045K73. He said the spring actually works for 1st gen, 2nd gen, some years of tundra, and I think he mentioned 3rd gen compatibility as well. I'm going to try and install them possibly this weekend and will let ya'll know.
